The Omron C500-SP002 is a precision-engineered spacer module designed for the C500 series programmable logic controller (PLC) systems, serving as an essential component for maintaining organized and stable unit assembly. Its primary function is to physically separate and align PLC modules, ensuring proper spacing and optimal heat dissipation while preserving system integrity. Utilizing robust pressure-welded connections, the C500-SP002 guarantees stable and secure electrical interfacing across multiple modules, supporting consistent signal transmission and reliability. It is compatible with a variety of backplane configurations, offering flexibility for complex system layouts and modular expansion. With a maximum I/O capacity of 1,024 points—expandable up to 4,096 points through remote I/O integration—the C500-SP002 enables scalable system growth for large automation networks. The module could be implemented across industrial control setups in North America, Europe, Asia, and other global regions, providing durable construction, seamless compatibility, and efficient organization within Omron’s C500 PLC architecture.
