MTL5082 RESISTANCE ISOLATOR.

The MTL5082 connects to a 2-, 3-, or 4-wire resistance temperature device (RTD) or other resistance located in a hazardous area, isolates it and repeats the resistance to a monitoring system in the safe area.

The module is intended typically (but not exclusively) for use with Pt100 3-wire RTDs. Switches located on top of the module allow

selection of 2-, 3-, or 4-wire RTD connection. The MTL5082 should be considered as an alternative, non-configurable MTL5074, for use in RTD applications where a resistance input is preferred or needed instead of 4/20mA. The design is notable for its ease of use and repeatability. The number of wires which can be connected on the safe-area side of the unit is independent of the number of wires which can be connected on the hazardous-area side. The module drives upscale in the case of open-circuit detection.
