DRG-1520 Thermocouple/millivolt isolated safety Barrier

Picture Name

Classification:

DRG series

The thermocouple isolated safety grid converts the on-site thermocouple/millivolt signal into one or two standard 4mA ~ 20mA current signals for isolation and transmission to the safety side. This is an intelligent safety grid, with cold end automatic compensation function, the model and range of millivolt of thermocouple are set by computer or setting device.
