Schneider Electric TWDLMDA20DRT Programmable Logic Controller

The Schneider Electric TWDLMDA20DRT is a 24 VDC modular base PLC from the Twido family, delivering 20 I/O points in a compact base: 12 digital inputs and 8 outputs. It runs on a 24 V DC supply and is designed to be extended with Twido modular I/O expansion modules to tailor the control architecture for small to mid-size automation tasks. The outputs are specified for both transistor and relay configurations with a per-channel rating of up to 8 A, enabling direct switching of common actuators and signaling devices from the base. Programming is done in the TwidoSuite environment, a dedicated Schneider Electric toolset that simplifies ladder logic and function block programming for Twido hardware. Typical applications include machine control, simple conveyors, packaging lines, and other equipment that requires compact, low- to mid-range automation using 24 V logic. As of the current lifecycle information provided by Schneider Electric, the TWDLMDA20DRT is listed as a discontinued reference, with service, repairs, and spare parts no longer provided by the manufacturer. If you are maintaining legacy Twido deployments, this base remains compatible with the Twido ecosystem and can be integrated with the compatible expansion modules within the Twido modular base lineup.
