Overview
The MTL5541S Isolating Driver is a high-performance repeater power supply designed for 2- or 3-wire transmitters operating in hazardous areas. It provides a fully floating DC supply to energize field transmitters and repeats the current in a separate isolated circuit to drive safe-area loads.
The unit supports HART® communication, allowing bi-directional digital signals to be superimposed on the 4–20 mA loop current. Its compact DIN rail mounting and robust design make it ideal for control systems requiring both safety and accuracy.
Engineers choose the MTL5541S because it combines intrinsic safety certification with proven reliability across oil, gas, chemical, and pharmaceutical industries. It is often deployed in projects where ATEX, IECEx, and CE compliance is mandatory.
