DST-605 thermocouple input isolated safety barrier

Classification:

Thermocouple Input

DST-605X-EX-a/b-c/d type thermocouple is input to the isolation barrier at the detection end, and the thermocouple signal in the dangerous area is converted into the corresponding voltage or current signal/RS485 signal/switch signal and output to the safe area. The product requires independent power supply, input/output/power three isolation. This product can be used with a variety of thermocouple sensors. 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.
