GE IC660ELB906 Network Interface Module

Product Overview

The GE IC660ELB906 is a robust and high-performance Network Interface Module (NIM) designed for use within GE Fanuc’s Genius I/O system. Acting as the critical communication bridge between a controller (PLC or host device) and the Genius I/O bus, this module allows multiple I/O blocks to communicate over a single twisted pair network. Known for its field-proven reliability, compact size, and support for distributed control, the IC660ELB906 is ideal for applications where fast, deterministic I/O communication and flexibility are key requirements.

It supports auto-addressing, data integrity verification, redundancy, and diagnostic functions, making it an essential component for modern distributed control architectures across industries.

Technical Specifications

Product Applications

The IC660ELB906 is primarily used in distributed control environments where I/O blocks are spread across large or remote sections of a plant. Applications include:

• Manufacturing Automation: Central control of remote sensors, actuators, and motor starters on large production lines.

• Power Plants: Interface with switchgear, RTDs, and relays located in different rooms or substations.

• Oil & Gas: Control of distributed field equipment in hazardous and remote environments.

• Material Handling: Real-time communication between the control system and conveyor-based sensors or diverters.

• Water & Wastewater Plants: Scalable architecture to connect remote I/O for pumping stations and treatment systems.

• Mining and Metals: Rugged and distributed I/O support in harsh operating conditions for equipment like crushers, conveyors, and feeders.

Product Advantages

• Reliable Distributed Architecture: Enables modular, decentralized system designs with minimal wiring.

• Fast & Deterministic Communication: Ensures low-latency data exchange with time-sensitive I/O.

• Robust Diagnostics: Real-time fault detection, signal integrity monitoring, and status indicators.

• Wide Compatibility: Seamless integration with GE Fanuc Series PLCs and other Genius-compatible products.

• Compact Design: Space-saving form factor ideal for panel installations and dense I/O configurations.

• Industrial-Grade Build: Built to perform in demanding environments with vibration and electrical noise.

• Scalability: Supports up to 31 devices per Genius network, simplifying system expansion.

• Maintenance-Friendly: Clear LED indicators and robust error detection streamline troubleshooting.

Frequently Asked Questions (FAQ)

1. What is the function of the IC660ELB906?
   It serves as a communication interface between a PLC/controller and Genius I/O blocks via a serial network.

2. How many devices can be connected to a single Genius bus?
   Up to 31 devices or I/O blocks can be connected on one Genius bus.

3. Is the IC660ELB906 compatible with modern GE RX3i systems?
   Yes, it is compatible with RX3i, as well as earlier GE Series 90-30 and 90-70 controllers.

4. What is the maximum bus length supported?
   Up to 2000 ft (610 meters) with standard twisted pair cable.

5. Can the module be hot-swapped?

6. What type of LED indicators does it have?
   It features status LEDs for power, fault, and network activity.

7. Does it require a specific mounting style?
   Yes, it must be mounted via a DIN rail or to a panel using its base unit.

8. Is the module resistant to harsh environments?
   Yes, it includes industrial conformal coating and is certified for extended operating conditions.

9. What kind of communication protocol is used?
   Genius I/O uses a proprietary token-passing serial communication method.

10. What happens if the Genius network fails?
    All connected I/O blocks will enter a predefined safe state, and the controller will register a communication loss.
