The Schneider Electric TM3DQ8U is an 8-channel, sourcing transistor output module from the Modicon TM3 distributed I/O system. Designed for controlling 24V DC loads such as solenoid valves, indicators, and small relays, this module features sourcing (PNP) outputs with per-channel short-circuit protection and clear status indication. It is a cost-effective solution for expanding the output capacity of compatible Modicon PLCs in industrial automation applications.
