Product Description
Omron’s CS1W-BI103 is a 10‑slot I/O expansion backplane for CS1/SYSMAC CS1 PLC systems, designed to extend I/O capacity while maintaining system integrity and bus performance. The rack accommodates up to ten I/O or bus units and supports panel or surface mounting for robust cabinet integration. It is technically compatible with CS-series and C200H-series I/O and bus units, enabling mixed-system expansions and migration use cases. The assembly operates in typical industrial environments from 0 to 55 °C and is intended for use within compliant control panels that meet applicable UL, CSA, and EC directives. This backplane is suited for applications requiring modular scalability such as process control, material handling, and machine automation where deterministic PLC backplane communication is required. The unit is supplied as the backplane/rack only; I/O modules, power supply, end covers, and mounting hardware are ordered separately. Use this backplane to build or extend medium-to-large CS1 PLC node configurations with consistent mechanical footprint and wiring layouts.
