Redundant Power Architecture and PLC Backplane Operation

The 140CPS22400 is specified as a redundant power supply module for the Modicon Quantum platform.

Its input range is 20 to 30 VDC, with 24 VDC identified as the nominal supply voltage.

The module provides 5.1 VDC output with an 8 A redundant power supply rating.

Internal overvoltage protection limits abnormal output conditions, while overload protection addresses short-duration excessive electrical loading.

A normally closed alarm contact provides a dedicated power supply fault indication for external monitoring circuits.

The green PWR OK LED provides local visual indication of power supply operating status.

The module accepts an input interruption up to 100 ms, with a specified 1 ms limit at 20 V.

Field Installation Guidelines

Install the module according to the Modicon Quantum rack and power distribution documentation.

Verify the 24 VDC source remains within the specified 20 to 30 VDC input range during operation.

Use the specified 5 A slow-blow fuse for the associated input protection circuit.

Maintain correct polarity and secure all power terminals before energizing the rack.

Separate DC power wiring from high-current switching conductors and high-noise signal cables where practical.

Route alarm wiring separately from high-energy conductors when the alarm contact connects to external monitoring equipment.

Connect cable shields according to the system grounding design and avoid creating unintended ground-current paths.

Confirm that rack ventilation maintains the specified 0 to 60 deg C ambient operating range.

Check the PWR OK indicator after energization and verify the external power-fault alarm circuit.

The 140CPS22400 was discontinued on December 31, 2022, with end-of-service specified for December 31, 2030.

The stated replacement is Schneider Electric BMXCPS4022, a redundant Modicon X80 power supply module rated for 24 to 48 VDC input.
