GE IC670GBI002 – Bus Interface Unit | GE Fanuc Series 90-70 PLC Platform
The GE IC670GBI002 is a Bus Interface Unit (BIU) designed for the GE Fanuc Series 90-70 programmable controller platform. In distributed I/O architectures, the BIU serves as the critical communication bridge between the remote I/O rack and the main CPU backplane — enabling high-speed, deterministic data exchange across the Genius Bus network. Procurement engineers sourcing replacement or expansion modules for legacy Series 90-70 systems will find the IC670GBI002 to be a direct, specification-matched solution.
At Konmask.com, every IC670GBI002 unit is individually inspected, function-tested, and shipped with full traceability documentation — ensuring your control system returns to operation without compromise.

System Architecture & Signal Flow
In a typical Series 90-70 distributed I/O configuration, the IC670GBI002 BIU occupies a slot in the remote I/O rack. The CPU communicates over the Genius Bus coaxial cable to the BIU, which then manages all I/O block transactions within its drop. The BIU handles address assignment, fault reporting, and data packetization — offloading bus management from the CPU and enabling scan times as low as 1 ms per drop at 1 Mbps bus speed.
Signal path: CPU Backplane → Genius Bus Cable → IC670GBI002 BIU → Local I/O Blocks (IC670MDL, IC670ALG, etc.)

Technical FAQ
Q: Is the IC670GBI002 compatible with the IC693 CPU series?
A: The IC670GBI002 is designed for the Series 90-70 I/O rack (IC670 family). It communicates with IC693 CPUs via the Genius Bus — the CPU must have a Genius Bus Controller (e.g., IC693BEM331) installed to interface with IC670 remote drops.
Q: Can this BIU be configured without Logicmaster 90?
A: Yes. Proficy Machine Edition (PME) v8.0 and later fully supports Series 90-70 hardware configuration, including BIU address and bus speed settings.
Q: What is the maximum cable length on the Genius Bus?
A: At 153.6 kbps, the Genius Bus supports up to 750 m (2,460 ft) of RG-6 coaxial cable. At 1 Mbps, the maximum distance is reduced to 75 m (246 ft).
Q: Do you offer exchange / repair services?
A: Yes. Contact support@konmask.com to discuss exchange pricing or board-level repair options for IC670GBI002 units with physical damage.
