Description
The GE Fanuc IC660BBD022 is a 24V DC, 16-circuit Discrete I/O block belonging to the Genius I/O family. This high-intelligence distributed I/O module is designed to provide decentralized control interface capabilities for GE Series 90-70, Series 90-30, and PACSystems RX3i controllers via the Genius bus.
Product Introduction
The IC660BBD022 is a “source” type discrete block that offers 16 flexible circuits. Each circuit can be independently configured as an input, an output, or a tri-state input (for broken wire detection). This versatility allows a single hardware module to handle various field device types, reducing spare parts inventory and cabinet space requirements.
As a “Smart” I/O block, the IC660BBD022 features advanced internal diagnostics. It can detect and report faults such as short circuits, overloads, and open wires directly to the controller or a handheld monitor. Its rugged design is specifically intended for industrial environments where high noise immunity and reliability are critical.

Technical Description & Key Features
The IC660BBD022 is distinguished by several “Genius” specific features:
- Configurable Circuitry: Unlike standard I/O modules, there is no fixed number of inputs vs. outputs. You can have 1 input and 15 outputs, or any other combination, set via software or a Hand-Held Monitor (HHM).
- Electronic Fusing: Each output circuit is protected by an electronic fuse. If a short circuit occurs, the block shuts down only the affected circuit and sends a diagnostic message to the PLC, allowing for rapid troubleshooting without manually replacing fuses.
- Hot Swappability: The block consists of two parts: the electronic assembly and the terminal base. The electronic assembly can be replaced without disturbing the field wiring, minimizing downtime during maintenance.
- Redundancy Support: The Genius bus supports GBC (Genius Bus Controller) redundancy, allowing the IC660BBD022 to communicate with multiple controllers in a high-availability architecture.
Product Usage Instructions
1. Hardware Setup
- Mount the terminal base onto a DIN rail or panel.
- Set the Block Address (0-31) using a Hand-Held Monitor (IC660HHM501) or through the PLC configuration software.
- Ensure the Genius bus is correctly terminated with a 75, 100, or 150-ohm resistor at the physical ends of the daisy-chain.
2. Wiring
- Power: Connect 24V DC to the power terminals.
- I/O: Wire field devices to terminals 1 through 16. Because this is a “Source” block, the module provides power to the field device.
- Shielding: Connect the Genius bus shield to the provided shield terminal to ensure communication stability in high-EMI environments.
3. Configuration
- Configure the circuit types (Input, Output, or Disabled) in your logic software (Machine Edition or Logicmaster).
- Enable “Pulse Test” if you require the block to periodically check the integrity of output loads.
