GE Fanuc IC697BEM733 Bus Expansion Module | Series 90-70 PLC Platform
Engineering Background
The GE Fanuc Series 90-70 remains one of the most widely deployed rack-based PLC platforms in heavy industrial environments worldwide. Designed for high-density I/O expansion and distributed control architectures, the Series 90-70 system relies on a robust backplane bus to maintain deterministic communication between CPU racks and remote I/O racks. The IC697BEM733 Bus Expansion Module is the critical hardware interface that enables this multi-rack topology, allowing engineers to extend system capacity without replacing the core CPU infrastructure.
Product Positioning
The IC697BEM733 is a bus expansion transmitter/receiver module engineered for procurement engineers and system integrators who require a verified, drop-in replacement or spare for existing Series 90-70 installations. Konmask.com supplies this module with full traceability, functional testing documentation, and rapid global dispatch — minimizing unplanned downtime in critical production environments.

System Architecture & Signal Flow
In a Series 90-70 multi-rack system, the IC697BEM733 is installed in both the CPU rack (as a bus transmitter) and each remote I/O rack (as a bus receiver). The module bridges the VMEbus backplane signals across the inter-rack cable (IC697CBL500 or equivalent), maintaining synchronous I/O data exchange between the CPU and all remote modules. Signal integrity is preserved over distances up to the rated cable specification, enabling flexible physical plant layouts.
Typical topology: CPU Rack [IC697BEM733 TX] → Expansion Cable → Remote Rack [IC697BEM733 RX] → I/O Modules

Technical FAQ
Q: Is the IC697BEM733 compatible with all Series 90-70 CPU models?
A: Yes. It is compatible with all standard Series 90-70 CPUs including IC697CPU731, IC697CPU771, IC697CPU781, and IC697CPU782 when used with supported rack configurations.
Q: Can I use IC697BEM733 to connect more than two racks?
A: Yes. Multiple remote racks can be daisy-chained using additional BEM733 pairs, subject to the maximum expansion distance and rack count defined in GE Fanuc Series 90-70 Hardware Reference Manual (GFK-0262).
Q: What cable is required between racks?
A: GE Fanuc IC697CBL500 (or equivalent shielded expansion cable). Cable length must comply with the system’s rated maximum inter-rack distance.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC and functional test report are available upon request at no additional charge.
Q: What is the lead time for bulk orders?
A: Standard orders (1–5 units) ship within 1–3 business days. Bulk orders (6+ units) are subject to availability; contact us for a dedicated lead time assessment.
