Structural Features: The NE2A-END is a compact, inline terminator that connects directly to the DeviceNet trunk line connector at the last node of the network. It is designed for easy installation without the need for additional tools.

Working Principle: In a DeviceNet network, signal reflections occur when electrical signals reach the end of a cable and bounce back, causing data corruption. The -END provides a 121Ω resistive termination that matches the characteristic impedance of the DeviceNet cable, absorbing the signal energy and preventing reflections.

Installation Requirements:

  • Install at the physical end of the DeviceNet trunk line
  • Ensure only one terminator is present at each end of the network
  • Connect using standard DeviceNet connectors
  • Verify network communication after installation

Usage Notes:

  • A DeviceNet network requires exactly two terminators (one at each end)
  • Do not install terminators at intermediate nodes
  • Verify the terminator is securely connected
  • Store in dry conditions
