TM3DQ16R 16-Channel Relay Output Module 2A AC/DC Screw Terminal | Schneider Electric

The Original New Schneider Electric TM3DQ16R is a 16-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 16 relay outputs (normally open, 2A per channel) with 8 channels per group and two common terminals. The relays can switch both AC and DC loads, offering flexibility for controlling contactors, solenoids, valves, and indicator lights. 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:
16 relay outputs (normally open) | 2 groups of 8 channels with independent commons | 2A per channel / 8A per common | 240V AC / 30V DC 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
