The MTT MS3708 is a slim plug-in frequency-to-analog converter that turns a pulse train from a flow meter, tachometer, or similar sensor into a proportional DC signal, delivered as one or two isolated outputs. It accepts a wide range of pulse sources, including dry contacts, open-collector outputs, AC or DC voltage pulses, and 4-20mA pulse signals, so it can be matched to whatever sensor is already installed without extra interposing hardware.
Where a dual-output configuration is used, both outputs stay isolated from each other, the input, and the power supply, letting one pulse source feed a control loop and an independent monitoring or logging system at the same time. Like the rest of the plug-in transmitter range, the MS3708 clips into its own socket base so the unit can be swapped for calibration or replacement in seconds 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.
