MTL 5500 Intrinsically Safe Isolators  MTL5581

MTL4581 – MTL5581 MILLIVOLT/THERMOCOUPLE ISOLATOR for low-level signals
The MTLx581 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 cable breakage; a second switch permits the selection of upscale or downscale operation as appropriate.
