Schneider Electric TM3DQ16TG Digital Output Module

Schneider Electric TM3DQ16TG is a 16-channel digital output expansion module for the Modicon TM3 family, designed to drive 24 V DC loads from compatible controllers such as M221, M241, M251 and M262. This TG version features transistor (PNP) source outputs and removable spring terminal blocks for quick field wiring. Each channel is rated for 0.5 A at 24 V DC, with a single common line capable of up to 8 A total, enabling multiple devices on one supply. The module provides 16 status indicators (one per output) that light green when the channel is active, aiding diagnostics. Wiring is unshielded and capacity supports field distances up to 30 meters. Weighing approximately 110 g, the TM3DQ16TG is designed for compact expansion within IP20-rated enclosures, making it suitable for machine-level I/O expansion in industrial automation setups. It integrates with EcoStruxure Machine Expert software for straightforward programming and configuration, and is part of Schneider Electric’s TM3 digital I/O ecosystem, offering modular expansion for TM3-based controllers. Typical applications include adding discrete control for conveyors, actuators, valve pilots, and other 24 V DC devices in automation cells, packaging lines, and factory automation projects.
