Schneider Electric TM3DQ8R Relay Output Module

The Schneider Electric TM3DQ8R is an eight-channel relay output expansion module for the Modicon TM3 discrete I/O family, designed to wire directly with screw terminals for field connections. It delivers eight relay outputs, each rated at 2 A, with a maximum of 7 A per common line, and supports loads up to 240 V AC or 24 V DC per channel, making it suitable for switching motors, valves, pumps, lights, and other actuators in compact automation panels. The module uses removable 5.08 mm pitch screw-terminal blocks, which simplifies wiring and maintenance in TM3 systems. As an expansion card, the TM3DQ8R integrates with the TM3 backplane to extend discrete control without requiring CPU changes, enabling scalable solutions for small to mid-size automation projects that demand reliable relay switching.
