MTT MS3104 Terminal Block Type High-Level Signal Conditioner (Isolator)

The MTT MS3104 terminal block signal conditioner takes a high-level DC current or voltage signal and delivers it as two independent, isolated DC outputs from a single unit — useful when one input needs to feed both a control loop and a separate recorder or alarm. Full isolation between input, both outputs, and power blocks ground loops and common-mode noise from reaching any of the connected equipment.

A choice of AC or DC power supply options lets the MS3104 fit into panels without a dedicated 24V DC bus, and the compact DIN-rail housing mounts directly where the field wiring lands. A fast-response option is available for loops where signal lag matters, and front-accessible zero and span trimmers keep on-site calibration quick.

It is a practical choice for distributing one high-level signal to two separate systems, isolating and re-scaling an existing loop, or protecting sensitive downstream equipment from ground loop currents.
