Product Description

The CR18-8DN relay module is a versatile industrial controller featuring 8 digital inputs and 8 relay outputs, designed for seamless integration with automation systems. The CR18-8DN module supports direct connection to sensors, actuators, and peripheral devices via its compact terminal blocks. It operates on a wide voltage range of 12-24V DC and functions reliably in temperatures from -20°C to 60°C, making it suitable for manufacturing, machinery, and process control industries. Key advantages include rugged construction, low power consumption, and RS-485/Modbus RTU communication compatibility. The CR18-8DN controller lacks built-in wireless connectivity and has a limited expansion capacity. It includes a 2.4-inch status display, a backup battery capacity of 2000mAh, and supports proximity detection up to 10mm. Its compact design optimizes space in control panels.
