TWDLCDA40DRF Schneider Twido Controller – 24 Inputs, 16 Outputs, PID, RS485

TWDLCDA40DRF Compact PLC Base – Twido Series

Brand: Schneider Electric | Series: Twido | Type: Compact Base Controller | Part No.: TWDLCDA40DRF

This 40‑I/O compact PLC base operates with a 24 V DC supply. It combines 24 discrete DC inputs with 16 outputs (2 transistor, 14 relay). The controller supports up to 7 expansion modules and features integrated non‑isolated RS485 serial link (Modbus/character mode master/slave RTU/ASCII, 38.4 kbit/s). Built‑in PID, event processing, and real‑time clock make it suitable for small to mid‑size automation tasks.
