Description
The General Electric Fanuc IC660BBD020 is a robust, highly reliable discrete output block belonging to the industry-trusted Genius I/O network series. Designed for demanding industrial automation environments, this block provides 16 discrete output channels rated for 24/48 VDC systems. It communicates via the high-speed Genius bus protocol, allowing distributed control architectures to reliably command field actuators, solenoids, and indicators while providing advanced diagnostics back to the master PLC.

🛠️ Operation Guidelines & Installation
Installation and replacement must be performed strictly by qualified industrial automation technicians or control system engineers. Always ensure that main input power, auxiliary power supplies, and field load voltages are completely locked out and de-energized before mounting or dismounting the block to prevent electrical shock or short-circuit damage. Secure the unit onto its designated mounting base (block electronics snap easily onto the removable terminal block base), ensuring proper shielding and termination of the Genius serial bus cables.
🔌 Power-Up and Power-Down Sequence
Verify that all field wiring terminals, power source connections, and Genius bus twisted-pair wires are correctly torqued and configured with proper bus terminating resistors before applying power. Energize the system control power and field power supplies to initialize the block. Observe the front-panel LED indicators (such as the I/O OK, Bus OK, and individual point status LEDs) to confirm normal diagnostic boot-up and network communication. For shutdown, isolate field power feeds safely before servicing.
📝 Product Usage Instructions
The IC660BBD020 block is configured via software tools (such as Proficy Machine Edition or Logicmaster) through the PLC configuration hardware catalog, where block node addresses and fault-reporting parameters are assigned. Routinely inspect terminal connections and verify that bus communication LEDs remain green to ensure uninterrupted data exchange between the block and the central controller.
❓ Common Questions (Q&A)
Q: What do the diagnostic LEDs on the block indicate during operation?
A: The “Bus OK” LED indicates successful communication over the Genius network, while the “I/O OK” LED shows that internal block hardware and power supplies are functioning normally. Flashing patterns point to specific configuration or network errors detailed in the manual.
Q: Can this block be replaced without rewiring the field devices?
- A: Yes, the Genius block design features a separate terminal block base (block electronics snap off independently), allowing you to replace a faulty electronic module without disturbing existing field wiring.
Q: Is this block compatible with modern PACSystems controllers?
A: While Genius I/O is a legacy platform, it can interface with newer PACSystems RX3i or Series 90-70 controllers using appropriate Genius bus controller (GBC) communication modules.
