Schneider Electric TM2DRA8RT

The TM2DRA8RT is an I/O expansion module designed for Modicon M238 logic controllers, providing 8 discrete relay outputs. Each output supports a maximum current of 7 A, with a per-channel rating of 2 A. The module is compatible with Twido and Advantys OTB interface modules, and can be easily mounted on a 35 mm symmetrical DIN rail.

Electrical isolation is a key feature, with 1500 V isolation between channels and an impressive 2300 V between the channels and internal logic, ensuring safe operation in various environments. The device demonstrates mechanical durability of up to 20 million cycles and an electrical durability of 100,000 cycles for various load conditions, including 2 A resistive loads at 240 V AC.

Current consumption is minimal at 30 mA at 5 V DC and 40 mA at 24 V DC when activated. The module includes a removable screw terminal block for electrical connections and features a local display for operational status indication. The dimensions of the module are 90 mm in height, 27.3 mm in width, and 84.6 mm in depth, weighing 0.11 kg.
