The MTT MS3759 Slim Plug-In Pulse to Relay Contact Converter takes dry contact, open collector, or wet contact input signals and converts them into clean relay contact outputs, giving control panels a reliable interface point between low-level field switching and equipment that expects a solid relay contact closure. It is available with either photo MOS FET (Form A) or mechanical relay (Form C) output stages, so it can be matched to applications that need fast solid-state switching or the wider voltage and current handling of a traditional mechanical relay.
Two independent, isolated outputs let one MS3759 drive two separate downstream circuits from a single field contact, which simplifies wiring in panels that need to fan a status or alarm signal out to more than one destination. A front-accessible switch lets technicians select between dry contact and wet contact sensing without opening the housing, while LED indicators for input state and relay activation make commissioning and troubleshooting straightforward. Four-way isolation between input, both outputs, power, and ground keeps the converter safely decoupled from noise and ground loops elsewhere in the system.
