Description
Overview
The IC670GBI002 Interface Module is a GE Fanuc Field Control Bus Interface Unit (BIU) designed to serve as the communication and power distribution backbone for distributed I/O networks. It provides regulated power, high‑integrity grounding, and stable communication links between Field Control I/O modules and host controllers, ensuring reliable operation in electrically demanding industrial environments.
Functional Characteristics
This module operates as the primary interface between the Field Control I/O stack and the control processor. It supports a wide input voltage range of 18–30 VDC (24 VDC nominal) and supplies regulated 6.5 VDC power to connected modules. The IC670GBI002 is engineered for noise‑sensitive installations and must be mounted on a grounded conductive DIN rail to maintain proper shielding and signal integrity.
Key electrical features include:
-
1.4 A output current capability
-
20 ms power‑loss hold‑up time
-
Precision voltage regulation for downstream modules
-
Support for high inrush currents (15–50 A peak)
-
47–63 Hz frequency tolerance
The module’s grounding strip is designed specifically for this BIU version and is not compatible with earlier “A‑series” terminal blocks.
