Surge Protective Device for 4~20mA & RS485
|
WTH-SG/TERWTH-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. Datasheet |

WTH-SG/PIPE SeriesTransmitter field instrumentation equipment is connected with peripheral lines through power lines and signal lines. It is extremely susceptible to damage from interference such as lightning in more complicated working environment. WTH-SG/PIPE-36 series Transmitter Surge Protective Device is specially developed for field instrumentation equipment in hazardous areas, etc. which are used to protect equipment from induced lightning current, surge voltage, electrostatic interference, radiation interference, internal overvoltage and other transient interference damage. WTH-SG/PIPE-36 series products are made of corrosion-resistant stainless steel and can be directly installed in hazardous areas on the field instrument. Fixed wires are connected to field instrument terminals like field cables. WTH-SG/PIPE-36 Threaded pipe installs the explosion-proof surge protective device in parallel on the 4-20mA control signal or twisted pair data signal (RS232, RS422, RS485) and other lines, protecting the system equipment (industrial monitoring equipment, automation equipment, etc.) against damages by over-voltage surge.
