I/O Bus Control Solution – GE IC660CBB902 | Series 90-70 PLC
Where This Product Is Used
The GE IC660CBB902 (also known as IC660CBB902K) I/O Bus Controller is a critical communication backbone module deployed across demanding industrial environments. Engineers specify this module in:
- Power Generation & Utilities – Turbine control panels, substation automation, and load-dispatch systems requiring deterministic I/O scan cycles.
- Oil & Gas Processing – Upstream wellhead controllers and downstream refinery DCS integration where bus integrity is non-negotiable.
- Automotive Manufacturing – Body-shop weld lines and paint-shop conveyors running GE Series 90-70 racks with distributed I/O drops.
- Pulp & Paper / Chemical Plants – Continuous-process facilities that rely on the Genius Bus for high-speed, fault-tolerant I/O communication.
- Water & Wastewater Treatment – SCADA-integrated pump stations and filtration systems using legacy GE PLC infrastructure.
- Food & Beverage Lines – High-throughput packaging and filling lines where bus dropouts translate directly to production loss.

Why Engineers Specify This Model
- Proven Bus Architecture – The Genius Bus token-passing protocol delivers deterministic scan times, eliminating the jitter that can cause nuisance trips in process-critical loops.
- Hot-Standby Redundancy Ready – Supports dual-bus redundancy configurations, enabling seamless failover without process interruption.
- Broad I/O Block Compatibility – Interfaces with the full GE Genius I/O block family: discrete, analog, bus interface units (BIUs), and motion blocks.
- Diagnostic Transparency – Onboard LED status indicators and bus-level diagnostics surfaced to the CPU allow maintenance teams to isolate faults to the block level without a laptop on the floor.
- Long Field Life – Designed for 24/7 continuous operation in industrial environments; many installations have run 15+ years without module replacement.
- Drop-In Replacement – IC660CBB902K is the updated revision of IC660CBB902; both are functionally interchangeable in existing racks.

Application-Specific FAQ
Q: Is the IC660CBB902K a direct replacement for the IC660CBB902?
A: Yes. The “K” suffix denotes a hardware revision with RoHS-compliant components. Both modules are functionally identical and slot-compatible in any Series 90-70 rack.
Q: How many IC660CBB902 modules can I install in one rack?
A: The Series 90-70 rack supports multiple bus controller slots. Most applications use one per bus circuit; dual-bus redundancy requires two modules configured as primary and secondary.
Q: Can this module communicate with GE RX3i or PACSystems CPUs?
A: The IC660CBB902 is native to the Series 90-70 backplane. For RX3i / PACSystems integration, a Genius Bus Interface Unit (BIU) such as the IC695GCG001 is required to bridge the two architectures.
Q: What cable type is required for the Genius Bus?
A: GE specifies Belden 9182 shielded twisted-pair (or equivalent) with 75 Ω termination resistors at both ends of the bus run. Maximum bus length is 750 m (2,460 ft) at 31.25 kbps.
Q: Do you provide a warranty on refurbished units?
A: Yes. All units carry a 90-day functional warranty. Extended 12-month warranty options are available for project-critical applications — contact us for details.
Q: Can Konmask assist with system integration or configuration?
A: Our technical team can provide configuration guidance, Logicmaster / Proficy ME parameter recommendations, and bus topology review. Contact [email protected] with your system details.
