GE IC660TBA026 Genius I/O Terminal Assembly

Configured for distributed bus signal termination in Genius I/O industrial control systems, the GE IC660TBA026, also cataloged as the IC660 terminal assembly, operates as a dedicated hardware component for field wiring distribution and backplane communication linking.

Suffix Breakdown & Model Matrix

The part numbering structure follows standard GE industrial hardware conventions:

• IC660: Designates the GE Genius I/O hardware product platform.
• TBA: Specifies a Terminal Block Assembly configured for passive field wire termination.
• 026: Identifies the specific electronic block mapping variant and pin configuration.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density

The terminal assembly maintains physical signal continuity for distributed nodes operating across token-passing communication architectures. By isolating field wiring terminations from active electronic blocks (such as the IC660EBA026 and IC660BBA026), the hardware architecture allows rapid module exchange without disturbing field-side wire loops. I/O density scaling and internal low-impedance copper conduction paths ensure stable signal throughput and deterministic bus update cycles across decentralized industrial networks.

Frequently Asked Questions

Q: Can the IC660TBA026 terminal assembly be separated from its electronic block while system power is active?

A: No. All system and field power supplies must be completely isolated and de-energized prior to disconnecting electronic blocks to prevent bus disruption and electrical arcing across terminal pins.

Q: Which electronic units are mechanically and electrically compatible with this terminal assembly?

A: The IC660TBA026 is engineered to interface directly with companion GE Genius I/O units including the IC660EBA026 bus interface block and IC660BBA026 base modules.

Q: What are the required tightening torque limits for the field wiring screw terminals?

A: Field conductors must be secured using calibrated drivers set between 0.5 Nm and 0.6 Nm to ensure secure clamping without stripping the terminal block threads.

Field Installation Guidelines

• Mount the terminal assembly securely onto a grounded standard DIN rail or directly to a backpanel using approved mechanical fasteners.
• Ensure all incoming shielded twisted-pair cables for the Genius Bus are properly terminated at designated grounding bars to minimize electromagnetic interference (EMI).
• Inspect all mechanical guide pins and connector receptacles for alignment prior to docking any electronic block modules to prevent bending or shearing pins.
