The GE Fanuc IC660TBR101, also cataloged as the IC660TBR101 Terminal Assembly, operates as a dedicated hardware component providing the mechanical and electrical termination interface for Genius I/O relay output blocks.

Hardware Specifications

Industrial Control Backplane Integration

The IC660TBR101 serves as the field-side physical interface for the IC660BBR101 Genius I/O relay output module. The assembly is engineered to facilitate reliable field wiring connections while maintaining mechanical stability within the Genius I/O network architecture. Deterministic signal transmission is achieved when the assembly is properly mated to the corresponding electronics assembly, ensuring that the normally open relay circuits are correctly routed to field devices. Proper thermal management and humidity control are required, as the assembly operates within the 0 deg C to 60 deg C range, and the high-density terminal layout necessitates correct wire management to prevent signal crosstalk.

Frequently Asked Questions

Q: Is this terminal assembly compatible with non-normally open relay modules?

A: The IC660TBR101 is specifically designed for compatibility with the IC660BBR101 relay output block; verify the pinout requirements if attempting to integrate with alternative Genius I/O series blocks.

Q: Does this assembly include protection circuitry for inductive loads?

A: This assembly provides the physical termination points. Surge suppression and protection circuitry are generally managed within the mated electronics assembly; ensure external suppression is added if field loads exceed relay contact ratings.

Q: What is the maximum humidity tolerance for long-term storage?

A: The terminal assembly is rated for 5% to 95% relative humidity; storage in environments exceeding this, or under condensing conditions, may compromise the terminal contacts and insulation integrity.

Field Installation Guidelines

• Mounting: Secure the terminal assembly to the mounting rail or cabinet backplane. Ensure firm mechanical engagement to prevent vibration-induced disconnection of the field wiring.
• Wiring: Terminate field wires according to the specified contact capacity of the terminal assembly. Use ferrules for stranded wires to ensure a secure, low-resistance connection at the screw terminals.
• Grounding: While the assembly acts as a passive interface, maintain common grounding points as specified in the overall Genius I/O system documentation to minimize potential differences across the I/O rack.
• Thermal Management: Although passive, the terminal assembly should be installed in a location with adequate airflow. In dense configurations, ensure vertical spacing to prevent localized heat buildup near the relay contact interfaces.
