Thermocouple input isolation safety barrier

1、 Overview of thermocouple input isolation safety barrier:

This product is manufactured and produced in accordance with the relevant standards of GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements" and GB3836.4-2000 "Electrical Equipment for Explosive Gas Environments Part 4: Intrinsic Safety Type" i "". The explosion-proof mark is Ex [ib] Ⅱ CT6, and it has been inspected by a quality inspection agency and obtained an explosion-proof certificate.

SWP8081-EX thermoelectric isolation safety barrier converts the on-site thermocouple/millivolt signal into two isolated standard 4-20mA/1-5V (temperature linear) signals and transmits them to the safety side output.
