TM3DQ8R 8-Channel Relay Output Module 2A AC/DC Screw Terminal | Schneider Electric

The Original New Schneider Electric TM3DQ8R is an 8-channel discrete output module for the Modicon TM3 I/O system, designed to expand the digital output capacity of Modicon M221, M241, M251, and M262 logic controllers. It provides 8 relay outputs (normally open, 2A per channel) with two isolated groups of 4 channels, allowing control of different voltage levels within a single module. A removable screw terminal block ensures secure field wiring. Part of the Modicon TM3 expansion family, it features a simple interlocking assembly mechanism for quick DIN rail mounting.

Core Engineering Highlights:
8 relay outputs (normally open) | 2 groups of 4 channels with independent commons | 2A per channel / 7A per common | 24V DC / 240V AC switching | 10 ms turn-on / 5 ms turn-off response time | 20 million mechanical cycles | 2300V AC isolation (output to logic) | Removable screw terminal block | IP20 protection | –10°C to +55°C horizontal operation

Technical Specifications:

System Compatibility:

• Schneider Electric Modicon M221 logic controllers 

• Modicon M241 logic controllers 

• Modicon M251 logic controllers 

• Modicon M262 logic controllers 

• EcoStruxure Machine Expert (formerly SoMachine) programming software

• Modicon TM3 I/O expansion bus

Installation Notes:

• The COM0 and COM1 terminals are not connected internally — each group of 4 outputs has its own independent common 

• For inductive DC loads, connect a free-wheeling diode in parallel to each load to protect the relay contacts 

• For inductive AC loads, use an appropriate external protective circuit (e.g., RC snubber) 

• Do not connect relay outputs to capacitive loads 

• For relay output (2A) wiring, use conductors of at least 0.5 mm² (AWG 20) with a temperature rating of at least 80°C (176°F) 

• For common conductors (7A), use conductors of at least 1.0 mm² (AWG 16)
