The OMRON C20H-CN311 is a 30 cm I/O connecting cable for legacy SYSMAC C-series programmable controllers. OMRON documentation identifies it for the C20H, C28H, C40H and C60H controller families, where it connects compatible I/O units in installed automation systems. The model was discontinued in March 2002 and OMRON lists no recommended replacement. Buyers maintaining existing equipment should verify the controller family, connector arrangement and required cable length before requesting a quote, because similarly named C200H cables are not the same model.
