MTT MS3711 Slim Plug-In Pulse Divider

The MTT MS3711 is a slim plug-in pulse divider that takes a high-frequency pulse train from a sensor or counter and scales it down to a rate that downstream displays, PLCs, or data loggers can work with. It reshapes and reconditions the incoming pulses along the way, so a noisy or irregular signal comes out the other end clean and isolated, with a division ratio that can be dialled in on site to suit the application.

It accepts a wide range of input types, from dry contacts and open collectors to AC or DC voltage and current pulses, and can drive two isolated outputs at once so one divided signal can feed a control system while another feeds a separate monitor or counter. Like the rest of the plug-in transmitter series, the MS3711 clips into its own socket base for fast swap-out during maintenance, and flexible AC or DC power plus wall or DIN rail mounting make it easy to fit into an existing panel.
