Schneider Electric TM2DRA16RT Discrete Output Expansion Module

The Schneider Electric TM2DRA16RT is a 16-channel relay output expansion module for Modicon M238 PLC systems that enables reliable switching of field devices. It expands discrete outputs to drive relays, solenoids, motors, and contactors across manufacturing lines, conveyors, packaging machines, and HVAC systems, with normally open relays and high isolation between channels and logic. Key specifications include 16 NO relay outputs, rated 24 VDC / 230–240 VAC, maximum 30 VDC / 264 VAC, up to 2 A per channel (8 A per common), response time ≤10 ms, isolation up to 2300 V, removable screw terminal block, 35 mm DIN rail mounting, and ~40 mA current draw at 24 VDC. It supports Modicon M238, Twido, and Advantys OTB platforms, with common replacements including Schneider Electric TM3DQ16R.
