Product Description

The 1SR-C04-A Controller, part of the SR-C04 Series Relay lineup, is a versatile automation module designed for industrial control systems. It features 4 digital inputs and 4 relay outputs (250V AC/5A), with direct expansion capability for up to 4 external modules. Supporting Modbus RTU via RS-485 communication, it operates at 24V DC (±10%) and functions reliably across -20°C to +60°C. Ideal for manufacturing, energy management, and machinery automation, this compact module offers easy integration, robust isolation protection, and low power consumption. However, its lack of built-in wireless connectivity and limited analog signal compatibility may require additional components for advanced applications. Its DIN-rail mounting design ensures quick installation in control panels.
