ABB 07KT97D 07KT97B 07KT97C GJR5253000R0162 ARCNET Communication Module

The ABB 07KT97D GJR5253000R0162, also cataloged as the 07KT97D Communication Module, operates as a dedicated hardware component for high-speed coaxial network communication within Advant Controller 31 and Advant OCS platforms.

Hardware Specifications

Deterministic Industrial Communication & Bus Isolation

The 07KT97D module establishes deterministic real-time communication across industrial networks via an integrated ARCNET interface. High-speed backplane bus communication velocity ensures rapid memory updates between host processors and peripheral network nodes. Full galvanic isolation between power rails, field I/O, and serial ports suppresses potential ground loops, while onboard firmware flash compatibility ensures persistent token-passing protocols over 93-ohm RG-62/U coaxial cable runs.

Frequently Asked Questions

Q: How is the physical layer terminated on an ARCNET coaxial segment using the 07KT97D?

A: The physical ends of the RG-62/U coaxial cable run must be terminated using standard 93-ohm BNC termination plugs to prevent signal reflections.

Q: What operational statuses are provided by the onboard diagnostic LEDs?

A: The green BS LED indicates active controller operation and PLC read/write execution, while the green TX LED illuminates when the unit transmits data packets over the network.

Field Installation Guidelines

1. Insert the 07KT97D module into its assigned rack slot, securing all retaining hardware to verify positive chassis grounding to the subrack frame.
2. Attach RG-62/U 93-ohm coaxial cable assemblies directly to the X4 BNC connector, locking bayonet connectors firmly in position.
3. Keep coaxial network cabling strictly separated from high-voltage AC circuits and variable frequency drive output cables inside panel wire ducts.
4. Verify that total segment cable length remains within the 305-meter limit for an 8-station ARCNET bus layout.
