GE Fanuc IC670GB1002 Field Control Bus Interface Unit
Configured for distributed network communication and local backplane power execution in Field Control architectures, the GE Fanuc IC670GB1002 (IC670GB1002 Bus Interface Unit) provides direct physical/electrical execution. The unit converts an incoming 18-30 VDC supply (24 VDC nominal) into a regulated 6.5 VDC backplane bus voltage delivering up to 1.4 A to adjacent expansion nodes. Operating with a continuous power consumption of 16.8 W, it maintains galvanic communication isolation while managing node data exchanges across the control bus network.

Backplane Bus Communication Velocity and Deterministic Networks
The GE Fanuc IC670GB1002 leverages optimized backplane bus communication velocity to manage deterministic data throughput across connected Field Control I/O modules. The internal power converter conditions incoming 24 VDC voltage to protect internal logic circuits against line transients while sustaining continuous bus arbitration. With an integrated 10 ms hold-up time during voltage dips, the module maintains firmware flash compatibility and prevents data corruption across high-density I/O clusters during power interruptions.
Frequently Asked Questions
Q: What are the primary power output limits for driving adjacent modules across the backplane?
A: The IC670GB1002 provides a regulated 6.5 VDC bus supply rated up to a maximum current load of 1.4 A. The total current draw of all connected downstream I/O modules must remain within this 1.4 A limit.
Q: How does the unit handle power supply transients during system startup?
A: The module accepts an input range of 18-30 VDC and tolerates an inrush current peak between 15 A and 50 A with a maximum duration of 3 ms. Integrated filter networks absorb line noise to maintain stable DC bus regulation.
Q: Is the IC670GB1002 compatible with hot-swap procedures during routine maintenance?
A: Yes. When integrated within supported GE Fanuc Field Control module bases, the unit allows safe hot-swapping of adjacent I/O modules without interrupting primary network node execution.
Field Installation Guidelines
Field installation personnel must observe strict mechanical and electrical standards during deployment:
- Secure the Bus Interface Unit to a grounded metal panel or standard DIN rail, ensuring low-impedance electrical contact with the mounting plate.
- Connect the 24 VDC power supply leads to the dedicated terminal block using recommended wire gauges to minimize voltage drop.
- Install external fuse protection on the 24 VDC supply line to protect against sustained overcurrent conditions.
- Route network communication cabling in separate wire ducts away from high-voltage motor circuits to suppress electromagnetic interference.
- Verify that total backplane current draw does not exceed 1.4 A prior to applying main power to the terminal bus.
