GE Fanuc IC660BBA106 Analog Input Block 6 Channels

IC660BBA106 GE Fanuc Current-Source Analog Input Block

Product Introduction

The IC660BBA106 belongs to the GE Fanuc Genius I/O family. This analog input block delivers six individually isolated channels. You can power it with 115 VAC or 125 VDC. Each input channel accepts 4-20 mA or 0-20 mA signals. The module provides a 24V current loop power supply for each channel. Input resolution reaches 1µA when you select a 200ms conversion time. Furthermore, the IC660BBA106 supports the Genius communication protocol for seamless integration with Series 90-30 PLCs.

Technical Specifications

The IC660BBA106 offers precision analog input measurement. Input accuracy equals 0.1% of full reading at 25°C. Thermal drift is 70 ppm per degree Celsius. Input impedance measures 100 ohms. Channel-to-channel isolation reaches 1500V RMS. Normal mode rejection is -45 dB at 50 or 60 Hz. Heat dissipation totals 12 Watts during normal operation.

Input Signal Range
Each of the six channels accepts 0-20 mA or 4-20 mA signals. The open circuit voltage is 24 VDC. Short circuit current stays below 75 mA. Maximum loop impedance is 1000 ohms for the 0-20 mA range. For the 20-25 mA range, maximum loop impedance is 800 ohms.

Resolution and Conversion Time
The IC660BBA106 lets you select input conversion times from 16.6 ms to 400 ms. This selection balances noise rejection against input resolution. Longer conversion times produce higher resolution. At 200 ms conversion time, resolution reaches 1µA. The module broadcasts 12 bytes of input data during each bus scan. Each input channel contributes two bytes of data.

Power Requirements

Connect the power source to terminals 6 and 7. Nominal power is 115 VAC or 125 VDC. The operating voltage range spans 93-132 VAC or 105-145 VDC. Frequency rating is 50 to 60 Hz.

Bus Switching Module Connection
If your application requires a bus switching module, connect it to terminals 8 and 9. The IC660BBA106 has a BSM circuit that is electrically common to input channel 1. This circuit remains isolated from the other five input channels.

Diagnostics and Alarm Features

The IC660BBA106 includes comprehensive diagnostic capabilities. Built-in diagnostics detect underrange, overrange, high alarm, low alarm, and open wire conditions. Each input circuit has two programmable alarm limits. One alarm triggers on a low value, and the other triggers on a high value. If either limit exceeds its threshold, the block indicates a fault. The module then sends a message to the handheld monitor.

Fault Reporting
You can enable or disable fault reporting as needed. The system automatically checks for over-range and under-range situations. The IC660BBA106 also supports circuit scaling and CPU redundancy. These features enhance system reliability in critical applications.

Communication and Compatibility

The IC660BBA106 uses the Genius communication protocol. Baud rate options include 38.4 kbaud or 76.8 kbaud. All Genius bus controllers work with this input block.

Programming Requirements
To configure the IC660BBA106, you need a handheld monitor. The monitor is required for configuration and control of this block. You can program upper and lower alarm limits for each input circuit using the handheld device.

Compatible PLC Systems
This input block works with Series 90-30 PLCs. It also supports Series Five, Series Six, and Series Six Plus systems. Check your CPU revision for specific compatibility requirements.

Terminal Assignments

The IC660BBA106 has 32 terminals for all connections.

Power Connections

• Terminals 6 and 7: Power source (115 VAC or 125 VDC)

• Terminals 8 and 9: Bus Switching Module connection

Input Connections
Terminals 10 through 32 connect to the self-powered inputs for the six analog channels. Each channel uses multiple terminals for complete signal wiring.

Status Indicators

The front panel of the IC660BBA106 includes two LED indicators. The Unit OK LED shows the module has power and passes self-tests. The I/O Enabled LED indicates active communication with the bus. During normal operation, both LEDs remain steadily ON. Different LED behaviors can indicate forced channels, disabled outputs, or a non-communicating block.

Installation Guidelines

First, mount the IC660BBA106 securely to a panel using the provided mounting holes. Next, connect the 115 VAC or 125 VDC power source to terminals 6 and 7. Then, wire your field devices to terminals 10 through 32 for the six input channels. Use appropriate wire gauges for signal integrity.

After completing all wiring, connect a handheld monitor to configure the block. Set the input conversion time for each channel based on your noise rejection needs. Program the high and low alarm limits as required. Finally, enable the Genius bus communication and verify both status LEDs illuminate steadily.
