The MS3709 is a high-reliability, slim plug-in pulse shaper (pulse isolator) designed to accept pulse train signals from process sensors or field devices, shape the waveforms, convert signal levels, and deliver clean, isolated outputs. Engineered to conserve space within packed control enclosures, this versatile instrument features an ultra-slim 29mm wide housing optimized for reliable wall or DIN rail mounting and provides an isolated single or dual output. The MS3709 supports multiple pulse input formats—including dry contacts, open collectors, AC voltage pulses, and 4-20mA DC current pulses—making it highly adaptable across diverse flow monitoring and speed-sensing systems. Built with comprehensive 4-way galvanic isolation rated for a 2000V AC dielectric strength, the pulse shaper completely protects delicate PLC inputs and SCADA systems from disruptive ground loops, high-voltage transients, and common-mode electrical noise.
Key Product Features
- Waveform Shaping & Level Conversion: Accepts distorted or low-amplitude pulse trains from a wide range of industrial sensors and cleanly shapes them into standardized square-wave pulses.
- Flexible Field Output Options: Field-configurable to deliver standard industrial output signals, including TTL levels, open collectors, and 10V or 12V DC voltage pulses.
- Robust 4-Way Galvanic Isolation: Provides an absolute electrical barrier between input, output 1, output 2, and power channels, featuring a 2000V AC dielectric strength for 1 minute and a 100MΩ minimum insulation resistance.
- Optional Pulse Hold Function (/T): Can be ordered with an integrated pulse hold capability, allowing users to stretch and extend short output pulse widths between 200µs and 500ms to match slow digital PLC inputs.
- Ruggedized Industrial Design: Enclosed within a flame-retardant UL94V-0 rated ABS resin shell featuring reliable M3.5 nickel-plated steel screw terminals and a premium factory-applied HumiSeal® polyurethane conformal coating for high moisture resistance.
