Schneider Electric 140CPS52400 Modicon Quantum Power Supply Module — 125VDC Redundant, 8A

The 140CPS52400 is a redundant DC power supply module for Schneider Electric's Modicon Quantum automation platform. It converts 125 VDC input power (100–150 VDC range) into regulated 5.1 VDC output for the Quantum backplane, delivering up to 8 A continuous current with built-in redundancy for high-availability industrial control systems.

• Backplane Power: Provides 5.1 VDC to all I/O modules, communication modules, and CPU in the rack
• Hot-Swappable: Quantum power supplies support hot replacement for maintenance without system shutdown
• Field Power Connector: Compatible with 140XTS00500 7-pin screw terminal connector (IP20)

Installation Guide

1. Install the 140CPS52400 into a dedicated power supply slot on the Quantum backplane.
2. Connect 125 VDC input power to the module's input terminals (observe polarity).
3. For redundant operation, install a second 140CPS52400 in the adjacent power supply slot.
4. Connect field power via 140XTS00500 connector if required for external I/O power distribution.
5. Verify power LED indicators on the module front panel after power-up.
6. Configure redundancy mode via Unity Pro or Concept programming software if applicable.

FAQ

Q: Is 140CPS52400 an analog input module or communication board?
A: No. Some third-party sources incorrectly describe it as an analog input module or communication board. The 140CPS52400 is a 125VDC redundant power supply module for the Modicon Quantum platform.

Q: What is the difference between 140CPS52400 and 140CPS22400?
A: 140CPS52400 accepts 125 VDC input. 140CPS22400 accepts 24 VDC (20–30 V) input. Both are redundant power supplies with 8A output.

Q: What is the difference between 140CPS52400 and 140CPS42400?
A: 140CPS42400 accepts 48–60 VDC input. 140CPS52400 accepts 125 VDC input. Output specifications are otherwise similar.

Q: Can I use 140CPS52400 in a non-redundant configuration?
A: Yes. It supports both standalone (single) and redundant (dual) configurations. In standalone mode, one module powers the entire rack.

Q: What is the maximum inrush current?
A: 28 A at 125 VDC during startup. Ensure upstream circuit protection is rated accordingly.

Q: Is 140CPS52400 compatible with M580?
A: No. 140CPS52400 is designed for Modicon Quantum racks. M580 uses different power supply architecture (e.g., BMXCPS series).

Selection Tips

• Quantum, 125VDC input, redundant power: 140CPS52400
• Quantum, 24VDC input, redundant power: 140CPS22400
• Quantum, 48–60VDC input, redundant power: 140CPS42400
• Quantum, 115/230VAC input, redundant power: 140CPS12400 / 140CPS12420
• Always verify: Input voltage (125VDC vs 24VDC vs 48VDC vs 115/230VAC), redundancy requirement, and rack slot availability
• Order compatible connector: 140XTS00500 7-pin screw terminal for field power distribution
