The Schneider Electric TM3DQ16RG is a 16-channel, relay output module from the Modicon TM3 distributed I/O system. It features 16 independent Form C (changeover) relay contacts for flexible switching of AC or DC loads, providing inherent electrical isolation between the PLC logic and load circuits. The "RG" suffix indicates a version with specific features, such as grouped or advanced diagnostics. This module is ideal for applications requiring control of diverse loads (e.g., solenoid valves, contactors, indicators) at different voltages.
