GE IC660BBR100M Relay Output Block for Genius I/O Systems

Description

Product Model: GE IC660BBR100M
Product Brand: GE Fanuc
Product Series: Genius I/O

Product Features:
• 16 independently grouped normally-closed relay output circuits (in four groups of four)
• Block power selectable between 115 VAC or 230 VAC via jumpers on terminal assembly
• High isolation between output circuit groups (1 500 VAC typical) for robust industrial separation
• Direct compatibility with Genius I/O rack systems, reducing wiring complexity and improving modularity

Product Role & System Fit

Within a typical rack-based I/O subsystem, the GE IC660BBR100M acts as the output block. Controllers or CPUs send their output commands to modules like this one, which then physically drive field actuators — contactors, solenoids, indicator lamps, relays, etc. Because it’s a “block” rather than a standalone module, you’ll usually find it mounted in a row of I/O blocks connected via a backplane or bus system.

In system architecture terms, the block sits downstream of the controller logic. The logic determines what should happen (by reading inputs, executing code, evaluating conditions) and then sends signals. The IC660BBR100M takes those signals and provides the power switching necessary to drive external devices. In many designs, the block’s outputs are relatively low current but feed further relays or contactors, possibly in a distributed control environment.

Compatibility is important: since this block uses the Genius I/O architecture from GE Fanuc, it shares its mounting, supply, wiring conventions, and diagnostics with other blocks in that family. This means maintenance teams, panel builders and system designers benefit from a consistent approach. If you standardize on the Genius I/O family, the GE IC660BBR100M becomes one of many building blocks and you don’t need special handling or custom adapters.

In retrofit use, this block is especially useful. Suppose you have an older system using relay rack assemblies and you want to modernize without ripping out everything. You can replace or add I/O racks using Genius I/O blocks like the IC660BBR100M, maintain existing wiring where possible, benefit from diagnostics, but keep the mechanical footprint the same. That reduces engineering cost, reduces downtime, and mitigates wiring errors.

From a system-fit perspective, one of the “hidden” advantages is maintainability. Because your mechanics, electricians and automation staff already know the Genius I/O environment, introducing the GE IC660BBR100M does not disrupt established practices. That means you gain technical benefits without re-training, re-drawing all panels, or redesigning the cabinet layout.
