Schneider Electric TM5SDI16D Digital Input Module

The TM5SDI16D is a 16-channel digital input expansion module for Schneider Electric's Modicon TM5 PLC system, delivering 24 V DC sink inputs in a 1-wire configuration. It plugs into the TM5 expansion bus to provide sixteen discrete digital inputs that capture on/off signals from field devices and feed them to the TM5 controller. Each channel uses a 24 V DC supply with sinking (NPN) topology and a single-wire interface for robust, simple wiring in industrial panels. Suitable for common automation tasks such as reading the state of pushbuttons, limit switches, and proximity sensors, the TM5SDI16D extends TM5 I/O capacity without a separate controller, enabling compact, scalable control architectures.
