Product Overview

The 140CPS11420 (Model: 140CPS11420) is a high-performance AC power distribution module designed for the Modicon Quantum automation platform. This module is engineered to provide stable 5.1 V DC power to the backplane, supporting the operational requirements of CPUs, communication modules, and I/O interfaces.

A key technical advantage of the 140CPS11420 (Part Number: 140CPS11420) is its "summable" architecture. Unlike standard standalone supplies, multiple 140CPS11420 units can be installed in a redundant-capable backplane to work in parallel. This configuration effectively increases the total current capacity from 11 A to 20 A, or provides N+1 redundancy for critical infrastructure where power failure is not an option.
