Signal SPD
SHANGHAI CHENZHU INSTRUMENT CO., LTD. is a very established provider that specialises in safety automation system. We have over 24 years of experience in the design and manufacture of intrinsic barrier, signal conditioner, surge protection device, safety relay,signal arrester, power transmitterand temperature transmitter. Our products and solutions cover many areas--from process automation safety to factory automation.
Electronic devices are always threatened by power surges and transients caused by power failures or nearby lightning strikes.
Signal SPDwas born to protect electronic devices in automatic control systems.
It is signal surge protectorfor field equipments such as sensors, transmitters, flow meters, solenoid valves, thermocouples, thermal resistance, devices with RS485 or RS232 interface and for I/O interfaces such as Al, AO, Dl, DO, Tl, Pl in PLC, DCS, FGS, ESD control systems.
It was widely used in petrochemical, gas, environmental protection and new energy industries.
Chenzhu also provides signal surge protection devicein intrinsical safety circuits that meet the same design and structural standards as intrinsic safety equipment, which requires certification and approval of them.
