24VDC 10A Redundant DIN Rail Power Supply | 240W | Internal ORing Diode | 120/230VAC Input | XCSF240CP
24VDC 10A Redundant DIN Rail Power Supply
The XCSF240CP is a 240W industrial DIN rail power supply designed for redundant 24VDC control power systems where equipment availability and continuous operation are critical. It provides a regulated 24VDC output at 10A continuous current and includes a factory-installed internal ORing diode, allowing multiple XCSF240CP power supplies to be configured for redundant operation without requiring a separate external redundancy module.
With adjustable 23–27.5VDC output, high temporary overload capability, DC OK monitoring, UL508 approval, and comprehensive electrical protection, the XCSF240CP is well suited for critical industrial automation and control applications where loss of 24VDC power could result in machine shutdown or production downtime.
What Does This Power Supply Do?
The XCSF240CP converts 120VAC or 230VAC input power into regulated 24VDC control power capable of continuously supplying up to 10A at 45°C.
The output can be adjusted from 23–27.5VDC, allowing voltage adjustment for specific equipment requirements or compensation for voltage drop in DC distribution wiring.
The key feature of the XCSF240CP is its built-in ORing diode for redundant parallel operation. When properly configured with another compatible redundant supply, a failure of one power supply does not necessarily interrupt 24VDC power to the connected control system.
Why Use a Redundant Power Supply?
In many industrial control systems, the power supply represents a single point of failure.
If a conventional 24VDC power supply fails, equipment powered by it—including PLCs, remote I/O, HMIs, industrial networking equipment, sensors, and control circuits—may immediately shut down.
A redundant power architecture uses multiple power supplies so that another supply can continue supporting the critical load if one power supply fails.
The XCSF240CP simplifies redundant system design by incorporating the required ORing diode directly into the power supply.
What Problem Does This Solve?
Unexpected loss of 24VDC control power can cause:
• PLC Shutdown
• HMI Shutdown
• Loss of Remote I/O
• Loss of Industrial Communications
• Machine Shutdown
• Process Interruption
• Production Downtime
• Loss of Monitoring or Control Functions
The XCSF240CP provides a practical way to build redundancy directly into the 24VDC power system, reducing the risk that failure of a single power supply will shut down critical equipment.

Why Choose the XCSF240CP?
The XCSF240CP combines 240W of regulated 24VDC power with built-in redundancy capability in one compact DIN rail power supply.
Its internal ORing diode eliminates the need for a separate external ORing diode when configuring a redundant power system, helping simplify panel design, wiring, and component selection.
The XCSF240CP also provides substantial temporary overload capability. Its 10A continuous output can increase to 15A for more than 30 seconds, providing additional capacity for startup and temporary overload conditions.
The integrated DC OK alarm contact allows a PLC or monitoring system to detect a power supply problem even if the redundant supply continues powering the load.
Need a Standard or Redundant Power Supply?
For standard 24VDC applications, consider the XCSF240C, which provides the same 24VDC 10A output without the integrated redundancy diode.
For critical systems requiring redundant power, the XCSF240CP includes the internal ORing diode needed for redundant parallel operation.
