PRODUCT DESCRIPTION

MTL3042 DC ISOLATOR 4/20mA loop-powered for I/P converters.

This unit acts like a direct-current transformer. Always powered from the safe-area side, it ensures that the same current flows in the safe and hazardous-area circuits and allows it to be controlled from either.

It is intended primarily for isolating and passing on a 4/20mA signal from a controller to drive a current-to-pressure (I/P) converter or a position actuator. If the loop is sensitive to the volt drop introduced by the unit, then the separately powered MTL3045 should be used. Note that the lower-cost MTL3043 can also be used for driving I/P converters in many closed-loop applications with integral control where its lower accuracy is acceptable.
