Applications: ABB's SB822 modules are widely used in the following fields: industrial automation, intelligent building energy management robotics. The PLC itself should be grounded according to the specified wiring standards and grounding conditions, and care should be taken to avoid using a common grounding wire with the frequency converter, and the two should be separated as far as possible when grounded. When the power supply voltage fluctuation is large, in order to suppress harmonic interference, noise filter or isolation transformer should be connected to the power line of the PLC power module and the input/output module. If the interference is still serious, measures such as reactors, transformers and noise filters should be considered in the main circuit of the inverter. When the frequency converter and the PCB are installed in the same electric control cabinet, the cables related to the frequency converter and the cables related to the PLC should be installed separately as far as possible, especially the strong current cable connecting the frequency converter and the weak current cable connecting the PLC should be installed separately.
