Working principle

When the industrial automation control system is running, when the PLC, DCS and other control systems issue digital control instructions, the instructions are transmitted to the ABB 3BSE020510R1 DO801 digital output module through the communication interface. After the module receives the instruction, the internal microprocessor parses and processes the instruction, and controls the corresponding output channel according to the instruction requirements.

For channels that require high-level (24V) output, the microprocessor controls the transistor to conduct, connecting the channel to a 24V power supply, thereby outputting a 24V DC signal to drive external devices to operate; For channels that require outputting a low level (0V), the microprocessor controls the transistor to turn off, disconnecting the channel from the 24V power supply and outputting a 0V signal, causing the external device to stop working.

During the entire process, the diagnostic circuit inside the module monitors the working status of each output channel in real time. Once abnormal conditions such as short circuit and overload are detected, the protection mechanism is immediately triggered to cut off the output of the corresponding channel, and the fault information is fed back to the control system through the communication interface for timely troubleshooting and handling.

Selection precautions

1 Channel Quantity Requirements

When selecting AI845 modules, the first step is to clarify the required number of analog input channels in the actual project. The number of analog signals varies in different industrial scenarios. For example, in a small automated production line, only a few analog input channels may be needed to collect temperature and pressure signals from key equipment; In large-scale chemical joint ventures, involving numerous production processes and equipment, the demand for analog input channels may reach hundreds or thousands. Therefore, accurately selecting the number of AI845 modules based on specific project requirements can not only meet system functional requirements, but also avoid resource waste and reduce costs.

2 Signal type and range matching

The types and ranges of analog signals output by different sensors vary. The AI845 module supports multiple signal types, such as voltage signals (such as 0-5V, 0-10V, etc.), current signals (such as 4-20mA), etc. When selecting, it is necessary to ensure that the AI845 module can adapt to the signal types output by on-site sensors, and its input signal range should cover the maximum and minimum values of the sensor output signal. For example, if a pressure sensor with an output of 4-20mA current signal is used on site, the selected AI845 module must be able to accurately collect current signals within this range, otherwise it may result in inaccurate signal collection and affect the normal operation of the control system.

​3 System Expansion Requirements

Considering the potential expansion needs of the project in the future, a certain amount of expansion space should be reserved when selecting the AI845 module. With the development of enterprises and the improvement of production processes, it may be necessary to add new analog signal acquisition points. If the system expansion is not fully considered during the initial selection, there may be module compatibility issues in the later stage, or a large-scale transformation of the entire control system may be required, which will bring high costs and time costs. Therefore, choosing AI845 modules with good scalability can provide convenience for future system upgrades and expansions.
