Schneider Electric TWDLCAA24DRF Compact Base Controller

Schneider Electric's TWDLCAA24DRF Compact Base Controller is a Twido PLC base designed for compact, extendable automation tasks, powered from 100–240 VAC. It provides 14 digital inputs (24 VDC) and 10 relay outputs and can accept up to four expansion I/O modules, with a dedicated serial-port slot and a cartridge interface for optional memory/RTC modules. The base includes two analog potentiometers for onboard adjustment and is part of the legacy Twido family; Schneider Electric marks it as discontinued as of September 27, 2024, with recommended replacements including Modicon M221 or M241 controllers (24 IO with relays) or TM3 IO modules, depending on the application.
