MTL5081 MILLIVOLT/ THERMOCOUPLE ISOLATOR With Good Price In Ready Ship

MTL5081 MILLIVOLT/

THERMOCOUPLE ISOLATOR

MTL5081 takes a low-level dc signal from a voltage source in a hazardous area, isolates it and passes it to a receiving instrument

located in the safe area. The module is intended for use with thermocouples utilising external cold junction compensation. A switch

located on top of the module enables or disables the safety drive in the event of thermocouple burnout or cable breakage; a second switch

permits the selection of upscale or downscale drive as required.
