Product Overview
When industrial automation systems require reliable communication between a host PLC and remote I/O, the GE Fanuc IC670GBI002 bus interface unit provides a proven solution. As part of the Field Control series, this bus interface unit (BUI) manages data exchange over the Genius Bus protocol, handling up to 128 bytes of input and 128 bytes of output per scan. It supports hosting up to eight Field Control I/O modules, making it suitable for medium-scale distributed control applications. The IC670GBI002 also supports Genius datagram communications and performs diagnostic tests on connected modules and itself, relaying information to a host device or handheld monitor.
Key Technical Specifications
The IC670GBI002 operates with a nominal supply voltage of 24 VDC (range 18-30 VDC) and also accepts a nominal rated voltage of 115 Volts AC or 125 Volts DC. Its voltage range covers 90 to 135 Volts AC or 105 to 150 Volts DC, with a frequency of 47 to 63 Hertz. Power consumption is 16.8 Watts, with maximum power at 115 Volts AC reaching 48 Volt-Amps at full load, and at 125 Volts AC reaching 24 Watts at full load. Inrush current is 15-50 Amps peak for a maximum of 3 milliseconds. The unit provides a power supply output of 6.5 VDC ±5% to modules, with a current output of 1.4 A. Holdup time is 10 milliseconds (maximum 20 milliseconds). The terminal block requires a maximum of 16 milliamps of current. Reliability is rated at more than 183,000 hours mean time before failure (MTBF).
Industry Applications
In manufacturing environments where reliable I/O communication is critical, the IC670GBI002 serves as a central interface between a Series 90-30, Series 90-70, Series Six, or Series Five PLC and field devices. For example, in a packaging line, the BUI can manage input from sensors and output to actuators across multiple I/O modules while performing self-diagnostics to minimize downtime. Its hot insertion and removal capability allows modules to be replaced without reconfiguring wiring, reducing maintenance time in continuous production settings.
Installation & Setup Guidance
Mount the IC670GBI002 on a standard DIN rail, ensuring the rail is connected to the grounding system and made of a good conductor resistant to oxidation. The unit installs onto a compatible terminal block for bus interface units, where power and communication cables terminate. Use wire gauge AWG #14 for connections. The module supports hot insertion and removal when used with appropriate Field I/O module versions, allowing replacement without disturbing wiring.
Maintenance & Reliability
With an MTBF of over 183,000 hours, the IC670GBI002 offers long-term reliability in industrial environments. Its operating temperature range is from 0 to 55 degrees Celsius, and storage temperature from -40 to 85 degrees Celsius, with non-condensing relative humidity of 5 to 95%. The unit is resistant to typical industrial noise levels when installed per guidelines. Regular inspection of connections and environmental conditions helps maintain performance.
Compatibility & Integration
The IC670GBI002 communicates via the Genius Bus protocol and is compatible with Genius handheld monitors version 4.6 or later. It works with host systems including Series 90-30, Series 90-70, Series Six, and Series Five PLCs. The unit supports CPU redundancy and hot standby CPU configurations, enhancing system availability.
