​Functions and Applications

TU515: As an I/O terminal unit, it is mainly used in the field of industrial automation to connect field devices with programmable logic controllers (PLCs). For example, on the automated assembly line in the manufacturing industry, various sensors (such as proximity sensors for detecting the position of workpieces, thermocouples for measuring temperature, etc.) and actuators (such as motor drivers for controlling the movement of robotic arms) can be connected to PLC through TU515 to achieve data transmission and control command issuance. It supports multiple signal types, including analog signals, digital signals, and temperature signals, and is compatible with various communication protocols such as Modbus, Profibus, and Profinet, making it easy to integrate into existing automation control systems.

TU516 (- H): Also an I/O terminal unit, specifically designed for analog and 24V DC digital modules. Among them, TU516-H has hot swappable function, which is of great significance in industrial production. For example, in some automated production processes that require uninterrupted operation, if a module fails, the operator does not need to stop the machine and can directly plug and replace the faulty module with power, greatly reducing equipment downtime and improving production efficiency. It uses spring terminals for a more stable connection and can adapt to complex industrial environments.

TU541: This terminal unit mainly serves 24V DC high current modules and uses screw terminals. In some large industrial equipment, such as the control system of high-power motors, the high current module in the control circuit can be connected and controlled through TU541. It can reliably carry and transmit high currents, ensuring stable system operation.

TU542: Used for 24V DC modules, with spring terminals, supporting up to 32 channels, divided into 4 groups of 8 channels each. Its flexible installation method (horizontal or vertical) and reliable grounding design make it suitable for control cabinets of various layouts. In the distributed control system of industrial automation production lines, TU542 can serve as an I/O connection unit for various nodes, efficiently transmitting signals from field devices to the control center.

Working principle

TU515: Adapt and convert different types of input signals through internal circuit structure. When the on-site equipment sends analog signals, it will convert them into digital signals suitable for PLC processing; For digital signals, they are directly matched in level and isolated before being transmitted to the PLC. In terms of communication, based on the supported communication protocol, the control instructions of the PLC are packaged into data packets that comply with the protocol specifications and sent to the field devices. At the same time, the data returned by the field devices is unpacked and transmitted to the PLC.

TU516 (- H): The principle is similar to TU515 when processing analog and digital signals. For analog signals, perform signal conditioning and analog-to-digital conversion; For digital signals, perform level conversion and signal shaping. The implementation of hot swappable functionality relies on its specially designed internal hot swappable circuit. This circuit can quickly cut off or restore the corresponding power and signal paths when detecting module insertion or removal actions, preventing current surges and signal interference generated during the plugging and unplugging process from affecting other parts of the system.

TU541: For high current modules, it uses conductor materials and electrical connection structures that can withstand high currents internally. When a high current is passed through a circuit connected by screw terminals, the terminals and internal circuit can effectively dissipate heat, avoiding equipment damage caused by the heat generated by excessive current. At the same time, through reasonable circuit layout and electrical isolation measures, ensure that high current circuits are independent of other low voltage and low current control circuits and do not interfere with each other.

TU542: Its channel design allows each channel to independently process input and output signals. The elastic contact method of spring terminals ensures a good electrical connection between wires and terminals in harsh industrial environments such as vibration and impact. During signal transmission, the input signal is buffered, amplified, and isolated to ensure accurate transmission to subsequent circuits. At the same time, the output signal is adapted to meet the driving requirements of on-site equipment.

Key points for use

Selection matching:

TU515: Select based on the signal type and quantity of on-site equipment, communication protocol requirements, and installation space. If there are multiple types of signals on site and integration with systems with different communication protocols is required, TU515 is a more suitable choice. At the same time, it is necessary to ensure that its rated current, voltage, and other parameters can meet the requirements of the connected equipment.

TU516 (- H): When there are analog and 24V DC digital modules in the system and there is a need for hot swappable functionality of the modules, TU516-H should be selected. For general analog and digital module connection requirements, a regular TU516 is sufficient. It should be noted that it matches the electrical parameters of the connected module, such as signal level, impedance, etc.

TU541: If it involves the connection of 24V DC high current modules, it is necessary to choose TU541. When selecting, it is necessary to ensure that the current carrying capacity of TU541 is sufficient based on the rated current of the high current module. Generally, a certain margin should be left to cope with possible instantaneous current surges.

TU542: Considering the number of channels and installation methods, if the system requires a large number of channels (up to 32) and installation space is limited, and flexible installation methods (horizontal or vertical) are needed, TU542 is the ideal choice. At the same time, attention should be paid to whether its rated voltage is consistent with the voltage of the connected circuit.

Installation specifications:

TU515: DIN rail installation method can be used. During installation, ensure that the rail meets relevant standards (such as TH35-15, 35x15mm mounting rail, in compliance with IEC 60715), and firmly install TU515 on the rail. The installation location should avoid environments with humidity, high temperature, and strong electromagnetic interference to ensure stable operation.

TU516 (- H): Pay attention to the wiring direction and fastening degree of the spring terminal during installation to ensure that the wire connection is firm. For the hot plug function of TU516-H, it is necessary to confirm that the system has taken corresponding safety protection measures, such as wearing anti-static wristbands, before performing the plug operation, to prevent static electricity from damaging the module.

TU541: Due to the use of screw terminals, appropriate tools should be used when wiring, and screws should be tightened to the specified torque to avoid safety hazards such as poor contact, heating, and even fire caused by loose screws. The installation position should be easy to operate and maintain, and convenient for subsequent inspection and fastening of screw terminals.

TU542: Whether installed horizontally or vertically, ensure that the mounting bracket is firm and reliable. When connecting wires, pay attention to the wiring method of spring terminals to ensure that the wires are inserted in place to ensure good electrical connection. At the same time, it is necessary to ensure reliable grounding of the equipment to prevent leakage and electromagnetic interference.

Maintenance inspection:

TU515: Regularly check its communication status, which can be checked for normal data transmission, packet loss, errors, etc. through the connected PLC or specialized communication testing tools. Check whether the appearance of the equipment is damaged or deformed, and whether there is dust accumulation on the internal circuit board. If there is dust accumulation, use specialized tools to clean it to prevent electrical short circuits caused by dust accumulation.

TU516 (- H): In addition to regular appearance and communication status checks, TU516-H with hot swappable functionality should undergo regular hot swappable function testing. Under simulated fault conditions, module hot plugging operations can be performed to check whether the system can respond normally, whether the module can work properly, and observe whether the hot plugging process interferes with other parts of the system.

TU541: Focus on checking the connection of screw terminals to see if there are any loose screws, oxidation or corrosion. Regularly measure the temperature at the terminal. If the temperature is too high, it may be due to poor contact or excessive current, and the cause should be promptly investigated and dealt with. At the same time, check the heat dissipation of the equipment to ensure that it can effectively dissipate heat during high current operation.

TU542: Check the working status of channels by testing input and output signals to verify whether each channel is working properly. Regularly check the elasticity of the spring terminals. If the elasticity weakens, the terminals should be replaced in a timely manner to ensure the reliability of the connection. In addition, it is necessary to check the grounding resistance of the equipment to ensure that the grounding meets safety standards.

ABB TK516 thermal overload relay

Functions and Applications

ABB TK516 thermal overload relay plays a crucial role in industrial electrical systems, mainly used for overload protection of three-phase motors. In actual production, electric motors often experience overload due to various reasons, such as sudden increase in mechanical load, improper motor selection, etc. If the overload situation cannot be dealt with in a timely manner, it will cause the motor winding to overheat, accelerate insulation aging, and in severe cases, even burn out the motor. The TK516 thermal overload relay can monitor the motor current in real time. Once the current exceeds the set overload threshold, it will quickly act, cut off the control circuit, and protect the motor from being burned out, ensuring the stable operation of production equipment. For example, in the large-scale ventilation fan system of a factory, if the fan motor is overloaded due to air duct blockage or other reasons, the TK516 thermal overload relay can respond in a timely manner to prevent motor damage and ensure the continuous normal operation of the ventilation system.

Working principle

Its working principle is based on the current thermal effect. When the motor is running normally, the thermal element inside the thermal overload relay generates heat through the normal working current, causing the bimetallic strip to slowly bend, but the degree of bending at this time is not enough to trigger the action mechanism. However, once the motor is overloaded, the working current increases sharply, the thermal element heats up quickly, the temperature rises rapidly, and the bimetallic strip bends faster due to uneven heating. When the degree of bending reaches a certain level, push the action mechanism to open the normally closed contact and close the normally open contact. In the control circuit, normally closed contacts are usually connected in series in the coil circuit of the AC contactor. When the thermal overload relay is activated, the normally closed contacts open and the AC contactor coil loses power, thereby cutting off the main power supply line of the motor and achieving overload protection for the motor.

Key points for use

Current setting value setting: Accurate setting of current setting value is the key to realizing the protection function of TK516 thermal overload relay. In general, the setting value should be set between 0.95-1.15 times the rated current of the motor. If the setting value is set too high, when the motor is truly overloaded, the thermal overload relay may not be able to operate in a timely manner and fail to provide protection; If the setting value is set too small, the motor may frequently touch the thermal overload relay during normal operation, causing the motor to malfunction. For example, for a motor with a rated current of 10A, the setting value of the thermal overload relay can be set at around 9.5A during light load operation; If it is running under overload, it can be set to around 11A.

Maintenance of connection contacts: It is crucial to ensure that the contacts of the thermal overload relay are tightly connected to the circuit. If the contact is not in good contact, additional resistance will be generated during operation, resulting in heating, which may cause the thermal overload relay to malfunction. Therefore, in installation and daily maintenance, it is necessary to regularly check the contact connections to ensure their firmness and reliability.

Reset operation: After the thermal overload relay is activated, the reset method should be selected reasonably according to the actual application scenario. In the case of unmanned operation on site, the reset mode should be set to manual reset to prevent the motor from automatically resetting and starting when the fault is not resolved, which may cause secondary faults or safety accidents. In scenarios where someone is on duty and can handle faults in a timely manner, automatic reset or manual reset can be selected according to the needs.

Circuit board circuit breaker

Functions and Applications

Circuit board circuit breakers are mainly used for overload and short circuit protection of circuits on circuit boards. In modern industrial automation control systems, circuit boards undertake important functions such as signal processing and control instruction transmission. Once the circuit on the circuit board is overloaded or short circuited, it may damage the electronic components on the circuit board and cause the entire control system to malfunction. Circuit board circuit breakers can quickly cut off the circuit when there is an abnormal increase in current, protecting the safety of the circuit board and related electronic equipment. For example, in the PLC control cabinet of an industrial automation production line, circuit board circuit breakers can effectively protect PLC circuit boards, communication circuit boards, etc., ensuring stable operation of the production line’s automation control.

Working principle

Circuit board circuit breakers typically use bimetallic or electromagnetic working principles. Bimetallic circuit board circuit breakers are similar to thermal overload relays, utilizing the thermal effect generated by current passing through the bimetallic strip. When the circuit is overloaded, the current increases, and the bimetallic strip heats up and bends. After reaching a certain degree, it pushes the release mechanism to operate and disconnect the circuit. Electromagnetic circuit board circuit breakers are based on the principle of electromagnetic induction. When a short circuit occurs in the circuit, the short-circuit current instantly increases, generating a strong electromagnetic force that causes the trip mechanism to quickly operate and cut off the circuit.

Key points for use

Selection and adaptation: When selecting a circuit breaker for a circuit board, it is necessary to ensure that its rated current, rated voltage, and other parameters match the actual working requirements of the circuit board. If the rated current is selected too low, the circuit breaker may trip frequently during normal operation of the circuit; If the rated current is selected too high, the circuit breaker may not be able to operate in a timely manner when the circuit experiences overload or short circuit. For example, for a circuit board with a working voltage of 24V and a normal working current of 2A, a circuit board circuit breaker with a rated voltage of not less than 24V and a rated current of around 2.5A-3A should be selected.

Installation position: The circuit board circuit breaker should be installed near the power input end of the circuit board to quickly detect abnormal currents in the circuit and cut off the circuit in a timely manner. At the same time, the installation location should be convenient for maintenance and repair, and easy to reset or replace after the circuit breaker is activated.

Regular inspection: Regularly inspect the circuit board circuit breaker to see if there is any damage, deformation, etc. on its appearance, and check if there is any burning phenomenon on the contacts. In addition, by simulating overload or short circuit tests, the sensitivity and reliability of the circuit breaker’s action can be detected to ensure that it can function properly in critical moments for protection.
