Working principle
REA 101 monitors fault current through overcurrent detection unit, and detects the light signal generated by arc light through arc light detection unit.

Installation settings: The sensor fiber end needs to be protected to avoid unnecessary triggering; When connecting expansion units, pay attention to the port switch settings, and the last expansion unit needs to be connected to a terminal resistor; Settings and configuration changes need to be made with the auxiliary power disconnected.

Core functions
Signal termination: The core function of TB850 is to terminate the CEX bus. In the CEX bus communication system, if the signal encounters an open circuit or mismatched impedance during transmission, reflection will occur, seriously affecting the communication quality. TB850 effectively absorbs signal energy, prevents signal reflection, and ensures stable unidirectional transmission of signals along the bus through specific circuit design and impedance matching, thereby improving the reliability of the entire communication system.
Stable Communication: By eliminating signal reflections, TB850 can significantly reduce communication error rates, minimize data transmission errors and losses, and ensure the accuracy and real-time data exchange between devices in industrial automation systems. This is crucial for application scenarios that require high communication stability, such as industrial production line control and automated warehouse management.
Working principle
When the signal is transmitted to TB850 on the CEX bus, its internal circuit will detect the arrival of the signal. The TB850 matches its impedance with the characteristic impedance of the CEX bus through a built-in matching resistor. According to circuit principles, when the load impedance is consistent with the characteristic impedance of the transmission line, all energy during signal transmission will be absorbed by the load without reflection. TB850 is based on this principle, which converts the signal energy transmitted over the bus into other forms of energy such as thermal energy, achieving effective termination of signals and ensuring the integrity and stability of the CEX bus communication link.
Key advantages
High reliability: ABB’s exquisite manufacturing process and strict quality control make TB850 have excellent reliability. In complex industrial environments, such as high temperature, high humidity, strong electromagnetic interference and other harsh conditions, it can still work stably, ensuring that CEX bus communication is not affected and providing solid support for the continuous operation of industrial automation systems.
Easy to install: The equipped 25 pin DB25P male connector and screw fixing method make the installation process of TB850 simple and fast. Even non professional technicians can easily complete the installation according to the operation manual, greatly saving the time and cost of equipment installation and maintenance.
Good compatibility: As a standard product of CEX Bus terminator, TB850 has good compatibility with many industrial automation equipment under ABB and third-party devices that comply with CEX bus standards. This enables users to easily select and integrate devices of different brands and functions when building complex industrial automation systems, enhancing the flexibility of system construction.
Precautions
Installation location: TB850 must be installed on the last unit of the CEX bus, which is crucial to ensure its proper functioning. Incorrect installation location may result in ineffective elimination of signal reflections, thereby affecting the performance of the entire communication system.
Environmental conditions: Although TB850 has certain environmental adaptability, it should be avoided to install it in extremely harsh environments as much as possible. For example, excessively high environmental temperatures may lead to a decrease in equipment performance or even damage, while highly corrosive gases may corrode the equipment casing and internal circuits. It is recommended to use within the environmental parameter range specified by the product, such as temperature and humidity.
Regular maintenance: To ensure the long-term stable operation of TB850, it should be inspected and maintained regularly. The inspection includes checking whether the connector is loose, whether the screws are tightened, and whether there is dust accumulation on the surface of the equipment. If any problems are found, they should be dealt with in a timely manner, such as re tightening the connectors, cleaning dust, etc.
