GE IC660TBD024 Genius I/O Terminal Block Assembly

The GE IC660TBD024 serves as the primary IC660TBD Terminal Block Assembly utilized to execute physical field wiring termination and bus power routing across Genius I/O bus interface platforms. This terminal block component interfaces with the IC660BBD024 block electronics assembly and IC660EBD024 electronics unit, providing terminal connections for field devices and Genius bus cabling.

Hardware Specifications

Backplane Bus Communication & IO Density Scaling

The terminal block assembly routes differential serial signals across the backplane bus communication velocity framework, providing continuous pass-through connectivity for the Genius I/O shielded twisted-pair bus. Engineered for I/O density scaling, the terminal base isolates field terminal wiring from the plug-in electronics module, enabling hot-swapping of the active logic board without disturbing field wiring. Internal bus connection points maintain firmware flash compatibility and low-impedance signal paths for uninterrupted scan synchronization.

Frequently Asked Questions

Q: Can the IC660TBD024 terminal block be replaced without disconnecting field wiring?

A: No, the terminal block itself holds the physical field wiring connections. However, the associated electronics unit (IC660BBD024/IC660EBD024) can be unbolted and replaced from this terminal base without disconnecting field wires.

Q: Does the IC660TBD024 terminal assembly contain active electronic circuitry or CPU logic?

A: No, the IC660TBD024 is a passive mechanical and electrical terminal assembly containing screw terminals, bus connectors, and mounting hardware for the active electronics module.

Q: How is serial Genius bus shielding terminated on the IC660TBD024?

A: Serial bus shield drain wires connect directly to designated shield terminals on the terminal block, which link to the panel ground via the assembly ground connection.

Field Installation Guidelines

• Disconnect all field voltage sources and Genius bus supply lines before mounting or wiring the terminal assembly.
• Secure the terminal base firmly to the cabinet panel using metal mounting screws to establish a frame ground connection.
• Strip field wires to the recommended length and torque terminal screws properly to avoid loose high-resistance contacts.
• Daisy-chain the Genius serial bus cable shield drain wires through the designated shield terminals without grounding them at multiple field points.
• Ensure the active electronics module locking screws are fully tightened into the terminal base prior to restoring power.
