Schneider Electric TM2DRA16RT Relay Output Expansion Module

The Schneider Electric TM2DRA16RT relay output expansion module adds 16 discrete normally open relay outputs to a Modicon PLC, enabling your controller to drive motors, solenoids, relays, and actuators from a single expansion unit. Part of the Modicon TM2 Expansion I/O family (M238 / Twido compatible), it operates from a 24 VDC supply and supports per-channel switching of 24 VDC up to 30 VDC or 264 VAC with a maximum of 2 A per channel (8 A max on a common line). Isolation is 1500 V between channels and 2300 V to logic, safeguarding the PLC from fault conditions. Each output is NO with contact resistance ≤ 45 mΩ and fast response times (≤ 10 ms ON / ≤ 5 ms OFF). The module draws about 40 mA at 24 V DC when all outputs are active and uses a removable screw-terminal block for secure DIN-rail installation (35 mm rail). Dimensions are approximately 90 mm × 27 mm × 84 mm and weight around 0.145 kg, and it is rated for up to 20 million mechanical operations. Common applications include packaging machinery, conveyor systems, manufacturing equipment, textile machines, and process control installations where a PLC must drive multiple external devices through relay outputs. For replacement or upgrade, compatible substitutes include TM3DQ16R, BMXDDO1602, and TM3DQ16T.
