MTL5581 - mV/Thermocouple Isolator
Single channel, mV/THC input for low power signals
The MTL5581 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 enables or disables the safety drive in the event of thermocouple burnout or a cable breakage; a second switch permits the selection of upscale or downscale operation as the application requires.
