The MTT MS3725 is a slim plug-in high/low signal selector that compares two DC input signals and passes through whichever is higher or lower, converting the selected value into a standard, isolated output. It is a natural fit for redundant sensor setups, where a control system needs a single reliable reading drawn automatically from two independent transmitters, whether that means picking the higher of two pressure readings or the lower of two temperature readings for a safety interlock.
Selection sensitivity is tight enough to catch even small differences between the two inputs, and an optional fast-response version cuts the reaction time down to 10ms for applications that need a quicker switch-over. Like the rest of the plug-in transmitter series, the MS3725 clips into its own socket base for fast swap-out during calibration or maintenance without disturbing the field wiring, and flexible AC or DC power plus wall or DIN rail mounting make it easy to fit into an existing panel.
