Eaton MTL5531 is a single-channel, DIN-rail mounted safety isolator and repeater from Eaton's MTL5500+ series. It is designed to interface with 2-wire 4-20 mA transmitters in hazardous areas (e.g., Zone 0/1/2) and provide intrinsic safety (IS) protection by limiting energy to the field. This device delivers an isolated and conditioned 4-20 mA output signal to the control system in safe areas, ensuring reliable signal transmission while complying with international safety standards. Its compact design and high accuracy make it ideal for critical process control applications in industries such as oil and gas, chemical, and pharmaceutical.
