Product Overview

The OMRON C500-PS223-E is a dedicated CPU power supply unit engineered for the SYSMAC C500 series programmable logic controller (PLC) system. As an integral component of the C500 platform, this power supply module mounts directly to the backplane of the CPU rack, providing stable and regulated power to the CPU unit and all I/O modules installed on the same rack. The C500-PS223-E is renowned for its robust construction, reliable performance, and flexible input voltage configuration, making it a dependable choice for industrial automation environments requiring continuous operation.

Designed with a selectable dual-voltage input feature, this power supply accommodates either 100-120 VAC or 200-240 VAC power sources, allowing seamless integration into facilities with different regional power standards. Its compact form factor and backplane mounting design minimize wiring complexity and reduce the risk of connection errors, ensuring efficient use of panel space in control cabinets and machinery enclosures.

Technical Specifications

Key Features

• Selectable dual-voltage input (100-120 VAC or 200-240 VAC) enabling global deployment across different regional power infrastructures.

• High output capacity of 12 A at 5 VDC, delivering ample power for the CPU and multiple I/O modules on the same backplane.

• Backplane mounting design eliminates external power wiring to individual modules, simplifying installation and reducing maintenance time.

• Integrated 24 VDC output terminals with 0.8 A capacity, specifically designed to power DC input units without requiring an external auxiliary power supply.

• Built-in voltage selector jumper allows quick and tool-free configuration between the two input voltage ranges.

• POWER indicator LED provides immediate visual confirmation of proper power supply operation.

• RUN output terminal enables external monitoring of CPU operational status for system-level diagnostics and safety interlocks.

• Robust electrical isolation with 1,500 VAC dielectric strength, ensuring reliable operation in electrically noisy industrial environments.

• Wide operating temperature range from 0°C to 55°C supports deployment in unregulated industrial conditions without external cooling.

• Comprehensive protection features including overcurrent protection and fuse holder for serviceable replacement.

Applications

The OMRON C500-PS223-E power supply module serves as the foundational power source for SYSMAC C500 series PLC systems, which are widely deployed in legacy industrial automation installations worldwide. Typical applications include automated assembly lines, packaging machinery, material handling systems, conveyor controls, and process monitoring equipment in industries such as automotive manufacturing, food and beverage processing, pharmaceutical production, and plastics processing.

Due to its selectable input voltage and robust 5 VDC output capacity, this module is particularly suitable for multi-rack C500 configurations where multiple I/O modules are installed. The built-in 24 VDC output eliminates the need for external power supplies when driving DC input units, reducing component count and simplifying panel layouts. As this model has been officially discontinued by OMRON, the C500-PS223-E remains a critical component for maintaining and extending the service life of existing C500-based control systems, with many facilities still relying on these proven platforms for continuous production operations.

For system expansions or replacements, OMRON has designated the CJ1W-PA202 as the recommended successor model, providing a migration path from the C500 series to the more modern CJ series platform while maintaining compatibility with existing I/O configurations where adapters are employed.

Installation Notes

The C500-PS223-E must be installed in the rightmost slot of the CPU Rack, as specified in the SYSMAC C500 installation manual. Before applying power, verify that the voltage selector is correctly configured for the available input voltage range (short terminals for 100-120 VAC, open for 200-240 VAC). Ensure the total current consumption of all units mounted on the rack does not exceed the available capacity of 10 A at 5 VDC for I/O units. The 24 VDC output terminals provide up to 0.8 A; if connected I/O units require higher current, an external power supply must be used to prevent system shutdown.
