MTA/DGA-1100/1200(ib) Single-Channel and Detecting-Element Safety Barrier

 Functional Overview 

MTA/DGA--1100/1200 single-channel and detecting-element safety barrier is a modular card loading intrinsic-safe explosion-proof instrument. It provides field two -wired transmitter with isolation power, restricts dangerous 

energy entering into dangerous places, and transforms the 4-20mADC signal that comes from the field two -wired 

transmitter into isolated 4-20mADC or 1-5VDC signal. ( Please refer to functional schematic diagram for details)
