A: to protect the lower control loop. Second: weakening the effects of environmental noise on the circuit under test.
Three: restraining public grounding, frequency converters, solenoid valve and pulse interference to devices of unknown; while the lower-level device has limited pressure, frontal flow function transmitter, meters, converters, solenoid valve PLC/DCS input and output the faithful protection and communications interface.
KLG series rail structure, easy to install, and can effectively isolation: input, output, and power supply and ground potential. To overcome the inverter high and low frequency noise and disturb.
