Description
MTL4544: Dual Channel Transmitter Interface
The MTL4544 powers two transmitters in hazardous areas and repeats both signals to safe areas. It works with conventional 2-wire, 3-wire, and HART transmitters. This dual channel unit saves space while providing reliable signal isolation and digital communication support.
