24VDC 3.5A Redundant DIN Rail Power Supply | 84W | Internal ORing Diode | 90-264VAC Input | XCSF85CP
24VDC Redundant DIN Rail Power Supply
The XCSF85CP is a compact industrial DIN rail power supply designed for redundant 24VDC power systems where increased system availability and reliability are required. It provides a regulated 24VDC output at 3.5A continuous current and includes an internal ORing diode, allowing multiple XCSF85CP power supplies to be configured for redundant operation without requiring a separate external redundancy module.
With universal 90–264VAC input, adjustable 23–27.5VDC output, DC OK monitoring, high overload capability, and integrated protection, the XCSF85CP is well suited for critical industrial control and automation applications where loss of 24VDC control power can result in equipment shutdown or production downtime.
What Does This Power Supply Do?
The XCSF85CP converts 90–264VAC input power into regulated 24VDC control power with up to 3.5A continuous output at 50°C.
The key difference between the XCSF85CP and a conventional DIN rail power supply is its built-in ORing diode for redundant parallel operation.
Two XCSF85CP power supplies can be used as part of a redundant power architecture so that 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 applications, the power supply represents a single point of failure.
If one conventional 24VDC power supply fails, the PLC, HMI, communication equipment, sensors, I/O, and other control devices powered by it may immediately shut down.
A redundant power architecture uses multiple power supplies so another supply can continue supporting the load if one supply fails.
The XCSF85CP simplifies this architecture by incorporating the ORing diode required for redundant parallel operation directly into the power supply.
What Problem Does This Solve?
Unexpected loss of 24VDC control power can cause:
• PLC Shutdown
• HMI Shutdown
• Loss of Industrial Communications
• Loss of Sensor and I/O Power
• Machine Shutdown
• Process Interruption
• Production Downtime
• Loss of Monitoring or Control Functions
Using XCSF85CP power supplies in a properly designed redundant configuration can reduce the risk that the failure of a single power supply will shut down the entire 24VDC control system.

Why Choose the XCSF85CP?
The XCSF85CP eliminates the need for a separate external ORing diode when designing a redundant 24VDC power system.
Its integrated redundancy capability, DC OK alarm contact, adjustable output voltage, high temporary overload capability, and compact 40mm DIN rail footprint make it particularly well suited for control systems where maintaining 24VDC power is important to equipment availability.
The DC OK dry contact can also provide a signal to a PLC, alarm system, or monitoring device when output voltage drops below the specified threshold, helping maintenance personnel identify a power supply problem even when the redundant system continues operating.
