In industrial process control systems, signals often encounter unstable measurement signals, such as: various sensors are input to the control system; the current signal of the control system is output to the control frequency converter; the current signal of the pressure transmitter control system is output to On-site valves; the feedback signals of on-site valves are input to the control system, etc. Due to various interference reasons, the frequency converter, valves, and actuators often work unstable and abnormally. This requires the use of a signal isolation processor to solve this problem. question.
Signal pressure transmitters from different manufacturers have differences in their production processes, product performance, product wiring, etc., but the use occasions, product protection requirements and maintenance of signal pressure transmitters are basically the same.
1. Read the instructions carefully before use
2. When used as a signal pressure transmitter, the input end should be connected in series to the loop circuit and the output end should be connected to the sampling loop.
3. When used as an isolation distributor, the input terminal should be incorporated into the power circuit and the output terminal should be connected to the transmitter.
4. If it does not work properly, you should first check whether the wiring is correct, and pay attention to the reverse and positive polarity of the power supply, signal input, and signal output.
