English User Manual / Datasheet (Full Version)


1. General Description

140CRA21210C is a single‑port redundant DIO (Distributed I/O) drop interface module with integrated AC power supply for Schneider Electric Modicon Quantum PLC.
  • C suffix: Conformal coating for humid, dusty, corrosive environments (coated PCB).

  • Function: Connects Quantum backplane to remote DIO stations via serial link; supports redundant ring communication.

  • Key Difference from 140CRA21210: Conformal coated (harsh environment version).
