Safety Barrier
Functional Overview
MTA-1300 single-channel and operating-end safety barrier is a modular card loading intrinsic-safe explosion-proof instrument. It transfers the 4-20mADC signal which comes from regulator to every actuator, and restricts
dangerous energy entering into dangerous places.The isolation part adopts magnetic isolation technology,
and the measures of current limit and voltage limit. It not only improves intrinsic-safety explosion-proof function
but also increases the anti-interference ability of the system. It has been approved by the standard explosion-proof verification authority and its intrinsic-safe level is (ib)IICT6.
