The MTT MS3749 Slim Plug-In High-Frequency Pulse Shaper is designed to accept pulse signals from a wide variety of field sensors and switches and turn them into clean, uniformly shaped pulse outputs that control systems can count and process reliably. It works with dry contact closures, open collector outputs, AC or DC voltage pulses, 4-20mA current loops, and line driver signals, making it a versatile front end for flow meters, tachometers, encoders, and other pulse-generating instruments feeding into a panel.
Because it is built for high-speed pulse trains, the MS3749 can shape and isolate signals up to the tens of kilohertz range without distorting the pulse train, and it offers a choice of TTL, open collector, voltage, or line driver outputs so it can be matched directly to the receiving equipment. A front-panel polarity reversing switch lets technicians correct for wiring orientation on site, optional sensor excitation power simplifies cabling to two- or three-wire pickups, and four-way galvanic isolation between input, dual outputs, power, and ground keeps noise and ground loops from corrupting the pulse count. An optional pulse-hold function is also available for applications that need to stretch short pulses for downstream equipment to register reliably.
