MTT MS3102 Terminal Block Type RTD Temperature Transmitter

The MTT MS3102 terminal block RTD transmitter converts a Pt or Ni resistance signal into two independent, isolated DC outputs from a single unit — useful when one measurement needs to feed both a control loop and a separate recorder, alarm, or monitoring system. Full isolation between input, both outputs, and power keeps every connected device electrically separate, avoiding ground loop problems even when the outputs go to different systems.

Because it accepts a choice of AC or DC power, the MS3102 fits easily into panels that lack a dedicated 24V DC supply. The DIN-rail housing mounts right where the RTD wiring terminates, front-accessible zero and span trimmers make on-site calibration quick, and lead-wire compensation keeps readings accurate over longer cable runs.

It suits applications that need one RTD measurement distributed to two separate systems, panels without a low-voltage bus, or any critical measurement where redundant isolated outputs add reliability.
