        Overview Manuals Specifications Communication Application Scenarios Compatibility

        Features:

        • Supports communication for the duplexed V net router AVR10D and connects control network resources with compatible external equipment.
        • Provides a wide channel sampling range from 1 Hz to 100 kHz with a reference measurement accuracy of plus or minus 0.01 percent.
        • Supports online handling procedures with the communication cable connected before power-up, removal, or installation.
        Industrial control systems depend on reliable communication between supervisory networks and connected process equipment. Yokogawa VI451-11 S3 provides a communication interface for V net router applications where data must move between control infrastructure and connected devices. The module is associated with duplexed AVR10D router configurations, supporting communication continuity within distributed control environments. Typical applications include process plants, automation systems, and installations where network communication forms part of daily control operation.

        Yokogawa VI451-11 S3 combines communication functionality with defined electrical and environmental operating limits. The 100 to 120 V AC input supports integration into industrial power environments, while the broad sampling range accommodates different signal and communication requirements. Stable reference accuracy further supports applications where dependable data handling is important. The module can therefore serve as part of communication architectures connecting control systems, PLCs, sensors, or other compatible network equipment.

        Maintenance and module replacement procedures are also important in systems where downtime needs to be minimized. Yokogawa VI451-11 S3 can be handled online when the specified cable connection procedure is followed. Keeping the cable connected during removal and connecting the cable before installation helps maintain an orderly service process. Combined with operation from 0 to 50 degrees Celsius and up to 95 percent relative humidity without condensation, the module fits controlled industrial environments requiring structured communication hardware management.

        The VI451-11 S3 Yokogawa Communication Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        Yokogawa VI451-11 S3 is a communication module used with the V net router architecture of the duplexed V net router AVR10D. The module supports communication between the core control network and connected system devices, field equipment, third-party PLCs, or dedicated sensor and encoder networks. Its role is to provide a stable communication path within distributed control system installations where coordinated data exchange is required.

        For electrical operation, Yokogawa VI451-11 S3 uses a 100 to 120 V AC input and supports a maximum current of 20 A. The specified channel sampling rate ranges from 1 Hz to 100 kHz, allowing the module to accommodate communication and measurement-related tasks across a broad operating range. Reference measurement accuracy is rated at plus or minus 0.01 percent, supporting precise signal handling within compatible system applications.

        Yokogawa VI451-11 S3 operates from 0 to 50 degrees Celsius and can be stored between minus 20 and 70 degrees Celsius. The permitted operating humidity range is 5 percent to 95 percent relative humidity under non-condensing conditions. These environmental limits make the module suitable for controlled industrial cabinets, communication racks, and process automation environments where stable operating conditions are maintained.

        Handling procedures for Yokogawa VI451-11 S3 require the communication cable to remain properly connected during installation and online replacement procedures. Power should be switched on only after the cable has been connected to the module. When removing the module online, the cable should remain connected, and online installation should also be performed after connecting the cable. These procedures support orderly integration of the communication module within the duplexed V net router system.
