Product Description

The K631-04RD relay module is a versatile 04RD control module designed for industrial automation applications, featuring 4 digital inputs and 2 relay outputs to directly interface with sensors, actuators, or peripheral devices. Compatible with RS-485 and CAN communication protocols, the K631 relay module supports seamless integration into distributed control systems, connecting up to 4 expansion modules in series for scalability. Operating within a wide voltage range of 10-30V DC and temperature tolerance of -20°C to +70°C, it ensures reliability in harsh environments such as manufacturing, energy management, and process automation. Its compact design (95x65x25mm) optimizes panel space, while screw-terminal wiring simplifies installation. While lacking a built-in display or battery backup, the K631-04RD excels in real-time signal processing with a response time under 10ms, making it ideal for time-critical control tasks.
