SYSMAC-C28K PLC

The SYSMAC-C28K series comprises compact programmable logic controllers (PLCs) manufactured by Omron as part of the broader SYSMAC-C family. These controllers are designed for industrial automation and machine control applications.

The C28K models combine input and output points in a single compact unit, with program storage available via removable ROM or internal RAM and battery backup for program retention. The series includes variants distinguished by output type and power supply configuration:

• Relay output models (for example, C28K-CDR and C28K-CAR variants)
• Transistor output models (for example, C28K-CDT1 variants)
• AC and DC input configurations across the range

All products in this series are Omron PLCs suited to compact machine control tasks where a fixed I/O controller is required.
