Schneider TM3DQ16TG | 16 NPN Sinking Transistor Outputs for TM3 PLCs

Product Description

The Schneider TM3DQ16TG is a discrete output expansion module from the Modicon TM3 series, engineered to expand the output capabilities of Modicon M221, M241, M251, and M262 PLCs. It provides 16 transistor outputs with NPN sinking logic, operating at 24 VDC, making it ideal for controlling relays, solenoids, lamps, and other low-power actuators.

Unlike sourcing-type modules, the TM3DQ16TG uses sinking outputs, which are preferred when the load is connected to a positive supply and the module switches the ground. Moreover, its HE10 connectors allow compact wiring and seamless integration into TM3 expansion systems.

With fast switching response times under 1 ms, LED diagnostics for each channel, and robust isolation between outputs and the bus, the TM3DQ16TG ensures reliable and safe operation in demanding industrial environments. Its slim design allows efficient panel space usage while delivering high-performance digital control.
