What is MTL MTL5044 Two Channel Repeater Power Supply?
The MTL MTL5044 Two Channel Repeater Power Supply is an industrial interface device designed to support intrinsically safe 4-20 mA measurement loops for field transmitters. It energizes and isolates two separate 2-wire transmitter loops located in hazardous areas, and repeats the transmitter current into safe-area measurement or control systems. This repeater power supply provides a fully floating DC supply and current repetition capability while maintaining signal integrity and safety compliance in demanding industrial environments.
In many industrial processes, instrumentation located in hazardous zones such as oil & gas, chemical plants, or marine environments requires safe and isolated power for sensors and transmitters. The MTL5044 fulfills this need by powering the field devices and transferring their signals safely to control equipment without exposing the system to hazardous area risks.
Key Features of MTL5044
The MTL5044 repeater has several robust features that make it ideal for process automation systems:
Two Independent Channels
Provides dual isolated support for two 4–20 mA loops, allowing simultaneous transmitter operation from one module.
Fully Floating DC Supply
