      Product Information:

      The 490NAA27103 is a long-distance Modbus Plus (MB+) backbone cable from Schneider Electric's industrial automation networking product line. As the foundational communication hardware backbone for building industrial bus LANs, it has a nominal length of 300 meters (approximately 1000 feet) and is packaged in unterminated, connectorless reels.

      The 490NAA27103 is primarily used for laying long-distance, high-speed token ring networks between cabinets and server racks in large industrial plants. It is specifically designed for use with Schneider Electric's classic Modbus Plus distributed junction boxes and can serve as the backbone cable for the entire control area.

      The 490NAA27103 cable uses a heavy-duty industrial-grade double-shielded twisted-pair (STP) construction, offering excellent tensile strength and abrasion resistance, while effectively blocking severe electromagnetic interference (EMI) generated by inverters, high-power motors, etc., ensuring zero signal integrity loss for 1 Mbps deterministic serial communication over a distance of 300 meters.

      Features:

      • Modbus Plus trunk cable - for Modbus Plus junction box - 300 m
      • Constructed as a robust Shielded Twisted Pair (STP) line engineered specifically to withstand industrial electro-magnetic interference (EMI)
      • Features free wire ends, allowing for manual stripping, terminal crimping, and custom field terminations
      The Schneider Electric 490NAA27103 is a high-performance shielded twisted-pair cable designed for efficient data communication, particularly suitable for Modbus Plus applications. Its extra-long 300-meter length meets various installation requirements, ensuring stable and reliable connections during deployment. The cable's free-end design allows for convenient and flexible electrical connections, easily meeting diverse application needs.

      Designed for clean indoor environments, this cable must be kept away from corrosive chemicals to maintain its integrity and performance. Its operating and storage altitude is limited to below 1000 meters, demonstrating excellent performance in high-altitude environments. This model is a reliable accessory suitable for a variety of industrial applications requiring robust data communication.

      The 490NAA27103 Schneider Electric Modbus Plus trunk cable may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
