The MELSEC-RJ71GP21-SX CC-Link IE Basic module enables high-speed, reliable industrial network communication with real-time control and seamless integration in automation systems.

Product Description

The MELSEC-RJ71GP21-SX is a CC-Link IE Basic module designed for industrial automation applications. It features 16 digital inputs and 8 digital outputs, supporting direct connection to up to 64 modules via CC-Link IE Basic. The module operates on a 24 VDC power supply (±10% tolerance) within a temperature range of 0°C to 55°C. It integrates an Ethernet port (10BASE-T/100BASE-TX) for seamless communication with PLCs and other devices, enabling real-time control in manufacturing and process industries. Known for its high-speed data transfer (up to 1 Gbps) and robust noise resistance, the RJ71GP21-SX excels in harsh environments. However, it lacks built-in battery backup and requires external surge protection. Typical applications include machine control, conveyor systems, and robotic assembly lines.
