GE Fanuc IC660TBR101 Genius I/O Terminal Assembly

The GE Fanuc IC660TBR101, also cataloged as the IC660TBR101 Terminal Assembly, operates as a dedicated hardware component for physical wire termination and circuit routing within GE Fanuc Genius I/O networks. This mountable base connects directly to the IC660EBR101 electronics module and IC660BBR101 relay output block, providing a permanent wiring platform that isolates field connections from active processing circuitry.

Hardware Specifications

Deterministic Network Routing and Backplane Bus Integration

The IC660TBR101 terminal assembly facilitates modular I/O density scaling across GE Fanuc distributed automation platforms. By separating physical relay wire terminations from active microprocessor electronics, the unit permits hot-swap maintenance of host modules without disrupting field wiring or requiring dedicated backplane bus communication velocity licenses. The internal terminal connections maintain continuous signal paths across deterministic networks like Profinet / EtherNet/IP and Genius bus loops under continuous operational stress.

Frequently Asked Questions

Q: Can relay output field wiring remain attached when replacing the active electronics module?

A: Yes, all field conductors remain landed on the IC660TBR101 terminal screws while the host IC660EBR101 electronic module is removed or serviced.

Q: Does the IC660TBR101 terminal assembly contain active relay contacts?

A: No, the IC660TBR101 is a passive terminal mounting base; the switching relays reside inside the host I/O block and electronics assembly.

Field Installation Guidelines

1. Panel Base Mounting: Attach the IC660TBR101 base firmly to the enclosure panel using screw fasteners before mounting the active electronics module.
2. Relay Wiring and Suppression: Land relay load wires on the designated terminal contacts. Install external surge suppression (RC networks or flyback diodes) across inductive field loads to prevent arc noise interference on adjacent bus lines.
3. Shielding and Separation: Maintain physical separation between high-voltage relay wiring and low-voltage communications lines within cabinet wireways to avoid noise coupling.
