Product Description
PRG-1500/1501 thermocouple/millivolt isolation safety barrier converts on-site thermocouple/millivolt signals into one or two standard 4mA~20mADC current signals for isolation and transmission to the safety side. This is an intelligent safety barrier with cold end automatic compensation function. The thermocouple millivolt model, range, etc. can be set through a computer or setter
