Schneider Electric TWDLCAA24DRF Twido PLC Base Unit

The Schneider Electric TWDLCAA24DRF Twido Micro PLC base unit is a compact, standalone controller that combines a 100–240 VAC power supply with 24 I/O points (14 digital inputs at 24 VDC and 10 relay outputs) for small to mid-size automation tasks. It accepts expansion with up to four I/O expansion modules, offers a Mini-DIN serial port supporting Modbus RTU/ASCII over RS-485 half duplex, and provides a memory cartridge or real-time clock cartridge slot for flexible programming and timing options. Mounting options include DIN rail or panel mount, and its typical applications span packaging machinery, conveyor systems, material handling equipment, pumping stations, and OEM industrial machines that require compact programmable control with expandable I/O. As a discontinued legacy controller in Schneider Electric’s Twido family, it is commonly replaced by TM221C24R or TM241C24R when retrofitting or upgrading control panels.
