Description

Foxboro DNBT P0971WV

Technical Specifications

  • Model Number: DNBT
  • Part Number: P0971WV
  • Function: Network Signal Termination

Functional Features

  • Impedance Matching: Precisely matches the characteristic impedance of the node bus cable.
  • Signal Integrity: Eliminates signal reflections that cause data corruption and communication errors.
  • Plug-and-Play: Simple installation at designated bus endpoints.

Application Scenarios
Required at both ends of every Node Bus segment in Foxboro I/A Series installations.

Performance Parameters

  • Frequency Response: Optimized for the specific signaling frequency of the I/A Series node bus.
  • Power Consumption: Passive device requiring no external power.

Material Composition
Precision resistors and network transformers encapsulated in a durable housing.

Structural Characteristics

  • Compact Design: Small form factor for easy panel mounting.
  • Bus Connector: Direct connection to the node bus cable or backplane.

Working Principle
The terminator absorbs the electrical energy of the data signal as it reaches the end of the cable, preventing it from bouncing back and interfering with subsequent data transmissions.

Installation Requirements
Install exactly one DNBT at each physical end of the Node Bus. Do not install terminators at intermediate nodes.

Usage Precautions
Missing or incorrect terminators are a leading cause of intermittent network faults. Always verify terminator placement during network troubleshooting.
