Description
ABB NINT-68
Technical Specifications:
- Network Type: Adapts to ABB proprietary control buses or standard fieldbuses.
- Termination Impedance: Built-in standard termination resistors (e.g., 120Ω or specific values).
- Interface Form: Dedicated bus interfaces or RJ45/terminal blocks.
Functional Features:
- Signal Conditioning: Amplifies and reshapes attenuated or distorted communication signals to extend communication distances.
- Termination Matching: Eliminates signal reflections at the end of the bus, ensuring accurate data transmission.
- Fault Isolation: Certain models feature network branch isolation to prevent single-point failures from paralyzing the entire network.
Application Scenarios:
Large distributed I/O stations, long-distance drive control networks, and internal communication bridging within complex control cabinets.
Performance Parameters:
- Communication Rate: Supports high-speed bus communication (e.g., 12Mbps or higher).
- Node Capacity: Effectively increases the load-bearing capacity of the bus.
Material Composition:
Industrial-grade electronic components with anti-static and surge protection designs.
Structural Features:
Compact modular design, typically installed at the physical end of the bus or branch nodes. Features network status indicators and wiring terminals.
Working Principle:
Provides impedance matching and signal buffering at the physical layer of the communication bus, ensuring the integrity of high-frequency digital signals during transmission and reducing the bit error rate.
Installation Requirements:
Must be installed at the physical end of the bus or designated repeater positions. Wiring must strictly adhere to network topology specifications.
Usage Precautions:
Termination resistor DIP switches or jumpers must be set correctly according to the network topology to avoid signal attenuation caused by multiple terminations. Verify module model compatibility with the network version before replacement.
