GE Fanuc IC670GBI002 Field Control Bus Interface Unit for Genius Bus

Product Overview

When industrial control systems require reliable communication between a host PLC and remote I/O, the GE Fanuc IC670GBI002 Field Control Bus Interface Unit provides a robust solution. This module acts as the header for each Field I/O system, managing data exchange over the Genius Bus. It supports up to eight Field Control I/O modules, handling 128 bytes of input and 128 bytes of output data per scan. Designed for demanding environments, the IC670GBI002 offers hot insertion and removal, minimizing downtime during maintenance or expansion.

Technical Specifications Breakdown

The IC670GBI002 operates with a nominal supply voltage of 24 VDC and accepts a supply voltage range of 18–30 VDC. It also supports a nominal AC input of 115 Volts AC, with a voltage range of 90 to 135 Volts AC or 105 to 150 Volts DC. Power consumption reaches 16.8 Watts at full load, with an inrush current of 15–50 Amps peak for a maximum of 3 milliseconds. The module provides a power supply output of 6.5 VDC ±5% at up to 1.4 Amperes to connected modules via the backplane. Its holdup time is 10 milliseconds, ensuring stable operation during brief power interruptions. The unit operates within a temperature range of 0 to 55 degrees Celsius and stores safely from -40 to 85 degrees Celsius, with non-condensing relative humidity from 5% to 95%.

Industry Applications

In manufacturing automation, the IC670GBI002 excels as a gateway between a central controller and distributed I/O points. For example, in a packaging line, it collects sensor inputs and sends actuator commands across the Genius Bus, reducing wiring complexity. Its support for hot standby CPU configurations enhances system reliability in critical processes like water treatment or material handling. The module’s resistance to industrial noise ensures consistent performance even near heavy machinery.

Installation & Setup Guidance

Mount the IC670GBI002 on a standard DIN rail with a minimum size of 108 millimeters (4.25 inches). Ensure the DIN rail is made of a conductive material resistant to oxidation and connected to the grounding system. Use a terminal block for bus interface units to terminate power and communication wiring. The unit accepts wire gauge AWG #14. For single or dual Genius Bus cables, follow the wiring diagram provided in the manual. The module supports hot insertion, so you can replace it without reconfiguring I/O wiring.

Maintenance & Reliability

With a mean time before failure (MTBF) of 183,000 hours, the IC670GBI002 offers long-term reliability. The associated terminal block is rated for 600,000 hours MTBF. To maximize service life, operate the module within its specified temperature and humidity ranges. Periodically inspect connections for corrosion or looseness, especially in humid environments. Since the unit is discontinued, plan for future replacements by verifying availability with BluePLC Industrial.

Compatibility & Integration

The IC670GBI002 communicates via the Genius Bus protocol and works with GE Fanuc PLCs such as Series 90-30, Series 90-70, Series Six, and Series Five. It also supports Genius hand-held monitors version 4.6 or later. The module is compatible with Field Control IC670G and IC670GBI series terminal bases. For redundant CPU setups, the unit supports hot standby configurations, enhancing system fault tolerance.

Selection Guide & Purchasing Advice

Before purchasing, confirm that your system uses the Genius Bus protocol and that the IC670GBI002’s voltage and power specifications match your installation. The product is discontinued/obsolete, so contact BluePLC Industrial to verify current stock and availability.
