Cost-Effective Basic Controller:Designed for small-scale automation systems and simple control tasks, offering reliable performance at an affordable price—ideal for entry-level industrial applications.
Integrated 14 Digital I/O Points:Provides 8 digital inputs (DI) and 6 digital outputs (DQ), meeting basic I/O requirements without the need for additional modules in small systems.
Relay Output Type:Features 6 relay outputs capable of switching both AC and DC loads, suitable for directly driving contactors, solenoids, lamps, and other devices in low-frequency switching applications.
Wide-Range AC Power Supply:Operates on AC 85–264 V, making it compatible with various global power supplies and industrial environments.
Standard RS485 Communication Port:Equipped with one RS485 interface supporting PPI and Modbus RTU protocols, enabling easy connection to HMIs, drives, and other serial devices.
Supports High-Speed Functions:Includes high-speed counters (up to 30 kHz); note that PWM/PTO pulse output is not available on relay-output models like CR40.
