Omron C20K-CDR-A Programmable Logic Controller Module

Omron C20K-CDR-A is a programmable logic controller (PLC) module from Omron's C20K line, designed to add digital input and output capacity to compatible PLC systems in industrial environments. It provides 8 digital inputs and 12 digital outputs, with a rated current of 2 A and a 100–240 VAC power range, enabling reliable operation from common mains supplies. As an I/O expansion module, it interfaces with the host PLC to read sensor signals, status indicators, and other digital inputs, and to switch actuators, relays, and other control devices, all within a single control network. The AC-powered design and multi-channel configuration make it well-suited for factory automation tasks such as machine control, process automation, and line integration where a robust, centralized control plane is required. Designed for installation in control cabinets alongside other Omron automation components, the C20K-CDR-A serves as a stable I/O backbone, consolidating multiple inputs and outputs into a single, scalable module that supports reliable, synchronized control across equipment and processes.
