Schneider Electric TWDLCAA24DRF Twido Base Unit

Schneider Electric Telemecanique TWDLCAA24DRF is a compact Twido Micro PLC base controller with integrated digital I/O, designed for standalone machine control in small to mid-size automation tasks. It provides 14 × 24 VDC digital inputs and 10 relay outputs (24 total I/O points), powered from 100–240 VAC at 50/60 Hz, and supports up to four I/O expansion modules to scale the system as automation needs grow. A Mini-DIN serial port enables Modbus RTU/ASCII RS-485 communication, while a memory cartridge or Real-Time Clock cartridge slot supports data storage options and time stamping for event logging. Mounting options include DIN rail or panel mount to suit panel-building preferences. Commonly used in packaging machinery, conveyor systems, material handling equipment, pumping stations, and OEM machinery, the TWDLCAA24DRF delivers compact, reliable control for process and machine automation in factory environments. As a discontinued legacy automation controller, it is often considered by engineers when replacing older Twido-based installations, with replacements such as Schneider Electric TM221C24R and TM241C24R available in the market.
