140CPS12420C
Schneider Electric
Overview
The 140CPS12420C is a Modicon Quantum in the Modicon Quantum range from Schneider Electric. It delivers stable control power at 5.1 V DC for Modicon Quantum racks.
Application & Technical Notes
As a modicon quantum, the 140CPS12420C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It conditions and distributes the low-voltage supply that powers the controller, I/O and communication modules on the same rack.
Key published characteristics include a 5.1 V DC rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Ensure adequate ventilation and do not overload the supply beyond its published current budget; consider redundancy for critical racks. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the 140CPS12420C, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the output voltage and current to the Modicon Quantum load and allow headroom for future expansion. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Description
| Note | The 140CPS12420C model from Schneider Electric is classified as a power supply module, intended for integration with the Modicon Quantum series. This component can accept an input voltage in the range of 115 V to 230 V and operates at an input current of 1100 mA. It possesses an inrush current rating of 19/38 A, providing necessary power during startup. This power supply has a rated power output of 130 VA, delivering stable performance for connected devices. The output voltage provided by this module is 5.1 V DC, making it suitable for specific applications within the Modicon systems. The associated fuse rating for the device is specified at 2A, utilizing a slow-blow type to accommodate potential peak currents without nuisance tripping. Weighing 0.65 kg, the module is manageable for installation and integration. An alarm output feature is included, capable of signaling power supply faults with a normally closed (NC) contact rated for 6 A at 220 V. To facilitate ease of monitoring, the device incorporates a local signaling LED that lights up green to indicate proper power operation (PWR OK). Additionally, the module includes internal provisions for output overvoltage protection, ensuring that connected equipment is safeguarded against voltage spikes. |
