Surge Protective Device for 4~20mA & RS485

WTH-SG/TER

WTH-SG/TER

WTH-SG/TER DIN rail surge protective devices for control signal are applied to the surge protection of 4~20mA control signal and twisted data pair (RS232, RS422, RS485 etc.), which can prevent various dialing equipment from permanent damage or transient interruption arising from inductive overvoltage, over current and other transient surge voltage caused by surge and industrial noise, etc.
