QJ71C24N-R4 Description

The ​​Mitsubishi QJ71C24N-R4​​ is a high-performance ​​serial communication module​​ designed for the MELSEC-Q series PLC system. It features ​​dual channels​​ (CH1 and CH2), both supporting RS-422/485 interfaces, and enables reliable data exchange in industrial automation environments. With a maximum transmission speed of ​​230,400 bps​​ (on CH1), it facilitates seamless connectivity with devices like (inverters), sensors, and external controllers using protocols such as Modbus. The module is compact (98 × 27.4 × 90 mm) and integrates easily into Q-series PLC racks, making it ideal for real-time control and monitoring applications .

 QJ71C24N-R4 Key Features

  • ​Dual-Channel Flexibility​​: Two independent RS-422/485 channels allow simultaneous communication with multiple devices, supporting 1:1, 1:n, and m:n network configurations .
  • ​High-Speed Data Transmission​​: Supports baud rates up to ​​230,400 bps​​ (CH1) and ​​115,200 bps​​ (CH2), ensuring efficient handling of large data volumes in real-time .
  • ​Multi-Protocol Compatibility​​: Works with ​​MC protocol​​, ​​Modbus​​ (via unsequential protocol), and bidirectional protocols, enabling versatile integration with PLCs,, and HMI systems .
  • ​Advanced Diagnostics​​: Includes error-checking features like parity verification and sum check codes, along with wire-break detection for reliable operation in noisy industrial environments .
  • ​Easy Configuration​​: Supports seamless setup with GX Works2 or GX Developer software; no IP address configuration is required for direct CPU connections, simplifying deployment .
  • ​Robust Isolation​​: Channel-to-channel electrical isolation minimizes interference, ensuring signal integrity over long distances (up to 1,200 meters for RS-485) .

QJ71C24N-R4 Material & Primary Applications

  • ​Material​​: The module is housed in a durable ​​industrial-grade casing​​ designed to withstand harsh conditions, including resistance to dust, vibration, and electromagnetic interference. It operates reliably within a temperature range of ​​0°C to 55°C​ .
  • ​Primary Applications​​:
    • ​Industrial Automation​​: Connects PLCs to (e.g., Mitsubishi E700 series) for motor control, enabling functions like speed adjustment and direction control .
    • ​Data Monitoring Systems​​: Integrates with sensors and SCADA systems for real-time data acquisition in sectors like energy management and manufacturing .
    • ​Process Control​​: Facilitates communication between PLCs and external devices in chemical, pharmaceutical, and HVAC systems for precise parameter monitoring .
