The AJ65SBTB2N-8R is a remote I/O module from Mitsubishi's MELSEC series, providing 8 relay output points. It is designed for distributed control systems in industrial automation, connecting seamlessly over a CC-Link network to enable centralized control.

Technical Specifications and Usage Details

    Output Specifications:

        Number of Outputs: 8 relay outputs
        Operating Voltage: 24V DC or 240V AC
        Current Capacity: Up to 2 A per output at 24V DC, and up to 8 A per common for 240V AC applications
        Response Time: Typically less than 10 ms for switching ON/OFF
        Isolation: Includes photocoupler isolation between outputs and internal circuits for added safety and reliability

    Network Requirements: Occupies a single CC-Link station, allowing straightforward integration into extensive industrial networks.

Commissioning and Recommendations

    Mounting and Connections: Ensure proper and secure installation, with connections following CC-Link network standards to prevent interference and signal loss.

    Initial Testing: Test each relay output to verify accurate response times and stable signal transmission.

    Routine Maintenance: Regularly check connections and clean as needed, particularly in environments where dust or moisture is present. Use GX Works2 or GX Developer software to monitor network health and diagnose any issues.

    Station Addressing: Assign a unique station number using the rotary switch to avoid conflicts on the network.

The AJ65SBTB2N-8R module is a reliable choice for industrial systems needing robust relay output control. Regular maintenance and careful setup will help ensure long-term, efficient operation in demanding environments.
