Product details

Overview

The 140CRA21110 is a Schneider Modicon Quantum DIO drop interface module, order code 140CRA21110, carrying 30 input and 32 output words over a single port. It operates on a 230 VAC supply and mounts on a Quantum backplane via a 7-pole terminal block, with a 3 A current output and 5.1 V voltage output.

This module acts as a remote DIO drop interface for the Modicon Quantum automation platform, mapping 30 input and 32 output words between the backplane and field devices. The 3 A current output on the 5.1 V rail powers the interface logic and field-side electronics; the 0.2 A switching current handles the internal relay or solid-state switching for discrete signals. Diagnostics cover RAM address and checksum at both startup and runtime, giving the controller visibility into module health without additional wiring. The 50 W power draw is the module's total consumption from the backplane — factor this into the Quantum power supply budget when populating a rack.

Applications

DIO drop interfaces like the 140CRA21110 are used in distributed I/O architectures within Modicon Quantum systems, commonly found in process plants, water treatment facilities, and material handling lines where remote racks consolidate field signals back to a central controller. The single-port design suits applications with a single remote drop per segment.

Within the Modicon Quantum family, the 140CRA21110 is a standard DIO drop interface — not a high-density or specialty module. It is specified by system integrators and plant engineers who need a straightforward remote I/O connection with UL 508, CSA, and DNV certifications, and who are already committed to the Quantum backplane architecture.

The 140CRA21110 carries certifications including UL 508, CSA Class 1 Division 2, DNV, C-tick, and GOST, and is listed with California Proposition 65 compliance. No official lifecycle status (active / phase-out / obsolete) is recorded in the available evidence; for current production status and last-time-buy windows, request a lifecycle check on the RFQ.
