Description
MTL4041B Single-Channel Isolator & Repeater for Hazardous Areas
The MTL4041B provides a fully floating DC power supply for 2- or 3-wire 4–20mA transmitters, including smart/HART® devices, located in hazardous areas. It safely repeats the analog signal to a safe-area load. This module supports bi-directional digital communication, allowing you to interrogate smart transmitters from a control system or a handheld communicator (HHC).
