TTPL Relay Modules

About TTPL Relay Modules

Trinity Touch Relay Card is a pre-assembled, multi-channel PLC interface module designed to simplify and speed up wiring between PLC outputs and field devices. Commonly used as a relay board, it integrates 4, 8, or 16 relays on a single DIN-rail mountable module, helping reduce panel space, wiring complexity, and installation time.

These relay cards are widely used in industrial automation control panels where multiple PLC digital outputs need reliable electrical isolation and signal amplification to operate high-load devices such as contactors, solenoid valves, motors, and alarms. Robust screw terminals ensure secure field connections, while optional Flat Ribbon Cable (FRC) connectors on the PLC side allow quick plug-and-play installation.
