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.

Frequently Asked Questions
What is the MTT MS3711 used for?
It sits between a pulse-generating sensor or counter and your downstream display, PLC, or data logger, dividing down a high-frequency pulse train to a rate the receiving equipment can read, while reshaping and isolating the signal along the way.
What division ratios can the MS3711 handle?
The division ratio is switch-selectable from 1/1 to 1/3200, so you can set it on site to match the pulse rate coming from your sensor to what your receiving instrument needs.
What’s the difference between the MS3711 and the MS3711A?
Both are slim plug-in pulse dividers in the same family. Send us your input pulse type, frequency, and required division ratio and we can confirm which model matches your application.
Can the MS3711 provide two separate outputs?
Yes — it can drive two isolated outputs at once, so one divided signal can feed a control system while another feeds a separate monitor or counter.
How do I know if the MS3711 is the right model for my application?
Send us your input signal type (dry contact, open collector, voltage, or current pulse), frequency, and the division ratio or output signal you need, and we can confirm before you order.
