QJ71C24N-R4 Mitsubishi Universal model Redundant Power Supply Module
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 .
