Description
MTL5082: Intrinsic Safety RTD Isolator Module
The MTL5082 is an easy-to-use, non-configurable isolator designed for use with 2-, 3-, or 4-wire RTD sensors in hazardous areas. It provides safe isolation and repeats the resistance signal to your monitoring system in the safe area. It is a perfect, simple alternative to a 4-20mA transmitter when a direct resistance output is needed. The module features open-circuit detection that drives the output upscale.

Installation Guide
- Connect your RTD sensor to the hazardous-area terminals.
- Terminal 1: RTD Input -ve
- Terminal 3: RTD Input +ve
- Terminal 4: 3-wire RTD Input -ve (compensation)
- Terminal 5: 4-wire RTD Input +ve (sense)
Connect your monitoring instrument to the safe-area output terminals (9, 10, 11, 12).
Apply power to terminals 13 (-ve) and 14 (+ve).
Use the switches on top to select the correct wiring mode (2, 3, or 4-wire) for your sensor.
