TM3DQ8RG

The Schneider Electric TM3DQ8RG is an 8-channel, relay output module from the Modicon TM3 distributed I/O system. It features 8 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 enhanced diagnostics or grouping features.
