The MTT MS3103 terminal block millivolt isolator takes a low-level millivolt signal and splits it into two independent, isolated DC outputs from a single unit — useful when one sensor needs to feed both a control system and a separate recorder or monitor. Full isolation between input, both outputs, and power blocks ground loops and common-mode noise across every connected device, which matters most with millivolt signals that are already vulnerable to interference.
A choice of AC or DC power lets the MS3103 fit into panels without a dedicated low-voltage supply, and the DIN-rail housing mounts directly where the low-level wiring terminates — converting to a robust signal as close to the source as possible. Front-accessible zero and span trimmers make on-site calibration straightforward.
It is well suited to strain gauge and load cell interfacing that needs to reach two separate systems, panels without a 24V DC bus, or any millivolt measurement where redundant isolated outputs add reliability.
