Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the 140CPS22400. Always verify electrical and mechanical compatibility before substitution:
- 140CPS12400 — Schneider Quantum 24VDC / 4A PS (lower current; suitable for lighter loads)
- 140CPS11420 — Schneider Quantum 115/230VAC PS (AC input variant; different input spec)
- 140CPS21400 — Schneider Quantum 24VDC / 8A non-redundant (single-supply configuration)
- 140CPS52400 — Schneider Quantum 24VDC / 8A enhanced redundant (upgraded variant)
- Third-party equivalents — Some aftermarket suppliers offer drop-in replacements; confirm backplane pinout, output ripple, and hold-up time compliance before use.
Note: Konmask.com recommends using OEM or certified-equivalent parts for safety-critical applications. Contact us for sourcing assistance.
Why Choose the Original Model
- Guaranteed Compatibility: Factory-validated for Modicon Quantum backplanes — no integration risk.
- Redundancy Architecture: Supports N+1 redundancy with automatic failover, minimizing unplanned downtime.
- Proven Reliability: Widely deployed in oil & gas, water treatment, and discrete manufacturing environments.
- OEM Support: Full Schneider Electric lifecycle support, firmware compatibility, and spare parts availability.
- Regulatory Compliance: Meets CE, UL, and IEC standards required for certified installations.
Typical Applications
- Modicon Quantum PLC racks requiring redundant DC power
- Oil & gas SCADA and DCS control panels
- Water and wastewater treatment automation
- Power generation and substation control systems
- Automotive and heavy manufacturing production lines
- High-availability process control where single-point power failure is unacceptable
System Compatibility
- Platform: Schneider Electric Modicon Quantum series
- Backplane: Compatible with standard Quantum I/O racks (140XBP series)
- Redundancy Module: Works with 140CRP93200 / 140CRP93100 Hot Standby CPU modules
- Software: Unity Pro / EcoStruxure Control Expert (no software configuration required for PS module)
- Input Source: Requires stable 24VDC supply; recommend UPS-backed input for full redundancy benefit
Selection Guide
Use the following criteria to select the correct power supply for your Quantum system:
- Step 1 — Calculate load current: Sum the current draw of all I/O modules, CPUs, and communication cards in the rack. Add 20% margin.
- Step 2 — Determine input voltage: 140CPS22400 requires DC 24V input. If your panel provides AC, select the 140CPS11420 instead.
- Step 3 — Redundancy requirement: For high-availability systems, use two 140CPS22400 modules in parallel redundant configuration.
- Step 4 — Rack slot count: Each PS module occupies one slot. Verify available slots in your 140XBP backplane.
- Step 5 — Environment: Confirm ambient temperature and humidity are within spec. For harsh environments, consider additional enclosure cooling.

Replacement & Compatibility FAQ
Q: Can I use 140CPS21400 as a direct replacement for 140CPS22400?
A: The 140CPS21400 is a non-redundant variant. It can power the rack but will not provide hot-standby failover. Only use it if redundancy is not required.
Q: Is the 140CPS22400 compatible with Modicon Premium or M340 platforms?
A: No. This module is designed exclusively for the Modicon Quantum backplane. It is not compatible with Premium or M340 racks.
Q: Can two 140CPS22400 modules be used together for redundancy?
A: Yes. Two units can be installed in the same rack for N+1 redundant power. The rack automatically switches to the backup supply if the primary fails.
Q: What is the lead time for this part?
A: Lead time varies by stock availability. Contact Konmask.com for current inventory status and delivery estimates.
Q: Do you provide a warranty?
A: Yes. Warranty terms depend on the unit condition (new vs. refurbished). Please enquire for details.
