DST-662 Current Output Isolated Safety Barrier

Classification:

Current analog output

DST-662X-EX-a/b-c/d type current output operation terminal isolation barrier, the safety zone from DCS or PLC and other electrical equipment through isolation and then output linear DC voltage/current signal, in order to drive the field actuator, the product needs independent power supply, input/output/power three isolation, can be used in the field solenoid valve, two-wire valve positioner, electrical converter and other equipment. According to GB/T 3836.1-2021 and GB/T 3836.4-2021, it has passed the inspection and obtained the ccc certificate. It is suitable for installation and use in safe areas and can be used together with intrapexy safety equipment in Zone 0, Zone 1 and Zone 2 of explosive gas hazardous places.
