Schneider Electric TM3DM8R Discrete Input Module

Schneider Electric's TM3DM8R is a Modicon TM3 discrete I/O expansion module that provides eight channels: four 24 V DC discrete inputs and four relay outputs. Each input operates at 24 V DC and draws about 7 mA, and the module uses removable screw-terminal blocks with a 5.08 mm pitch for quick, secure field wiring. Designed for TM3 controller racks, the TM3DM8R extends digital input and relay output capabilities for common industrial tasks such as machine sensing, interlock logic, and relay-driven actuation in compact panels. As part of the Modicon TM3 family, it offers straightforward integration and secure screw-terminal connectivity for TM3-based control architectures.
