The MTT MS3702-01 is a slim plug-in RTD temperature transmitter built for 4-wire RTD sensors, where separate excitation and measurement leads remove lead resistance error from the reading and hold accuracy over longer cable runs than a standard 3-wire connection allows. It linearizes the RTD signal and delivers it as one or two isolated DC outputs, with front-accessible zero and span trimmers for quick on-site adjustment.
Like the rest of the plug-in transmitter range, it clips into its own socket base so the unit can be swapped for calibration or replacement in seconds without touching the field wiring. Where a dual-output configuration is used, both outputs stay isolated from each other, the input, and the power supply, letting one 4-wire RTD feed a control loop and an independent monitoring system at the same time. Flexible AC or DC power and wall or DIN rail mounting make it easy to fit into an existing panel design, and standard upscale burnout protection helps flag a broken sensor rather than reporting a misleading reading.
