5X00062G01 5X00063G01 is a linear opto-coupler isolation principle, the input signal will first be modulated by semiconductor devices to transform, and then through the light-sensitive or magnetic sensing devices for isolation and conversion, and then demodulation and transformation back to the original signal before isolation or different signals, and at the same time the power supply to the signal after isolation of the isolation of isolation processing. Ensure the absolute independence between the transformed signal, power supply and ground. As long as there is interference in the place, the input end and the output end of the middle plus this product, generally can effectively solve the problem of interference. Now is an important part of the industrial automatic control system.

5X00062G01 5X00063G01’s PLC system has a large number of input and output points for digital and analogue quantities, and the problem of false connection of the wiring terminals sometimes affects the stable operation of the system and normal display. For this problem, we have taken regular inspection and fastening measures, and received good results.

5X00062G01 5X00063G01 in the transformation of the commissioning stage and later production operation during the individual hardware (DI module SM321, D0 module SM322, AI module SM33 1, A0 module SM332 and CPU413) damage failure, we have analysed the main wiring errors and lightning protection is not in place due to the string of strong electricity. Correct the wiring error, and then each analogue signal channel to increase the isolator and the lightning protection device to improve the hardware damage chances are greatly reduced.
