GE Fanuc IC660BBA105 Analog Output Block 6 Outputs

IC660BBA105 GE Fanuc Current-Source Analog 6 Output Block

Product Introduction

The IC660BBA105 belongs to the GE Fanuc Genius I/O family. Emerson Automation now manages this product line. This analog output module delivers six isolated outputs in the 4-20 mA range. You can power it with either 115 VAC or 125 VDC. The module offers 6µA resolution and 0.15% accuracy at 25°C. Furthermore, it supports the Genius communication protocol at baud rates of 38.4 or 76.8 kbaud. This block is compatible with Series 90-30, Series Five, Series Six, and Series Six Plus PLCs.

Technical Specifications

The IC660BBA105 provides robust analog output capabilities. The output range spans from 4 mA to 20 mA, with a full scale range of 0 to 24 mA. Update rate is 25 ms, and heat dissipation measures 12 Watts. Block-to-block isolation reaches 1500 Volts for one minute. The module contains 32 terminals for all field wiring connections.

Power Requirements
Connect the power source to terminals 6 and 7. The operating voltage range is 93-132 Volts AC or 105-145 Volts DC. Frequency rating is 50 to 60 Hz. No additional power supply is needed for the 4-20 mA current loops because the block provides isolated power to all outputs.

Output Characteristics
Each of the six outputs converts 12-bit digital signals to analog signals. Resolution is 6µA per count. Accuracy equals 0.15% of full scale reading at 25°C. Thermal drift is typically 35 PPM per degree Celsius. The outputs are electrically identical and share one common group.

Diagnostics and Fault Reporting
The IC660BBA105 includes comprehensive diagnostic features. It can detect output over-range and under-range conditions. The module also recognizes feedback signals below 1.5 mA. You can disable fault reporting if needed. Additionally, the block supports configurable output hold features. In case of a processor error, it can hold the last output state or switch to a default state.

Communication and Compatibility

The IC660BBA105 uses the Genius communication protocol. Baud rate options are 38.4 kbaud or 76.8 kbaud. All Genius bus controllers are compatible with this module.

Software Requirements
To configure the IC660BBA105, you need a handheld monitor with version 3.7 or above. The programming software must be Logicmaster 6 version 4.02 or later.

CPU Compatibility

• Series Six PLCs: revision 105 or later

• Series Six Plus PLCs: revision 110 or above

• Series Five PLCs: revision 3.0 or later

Bus Switching Module
If your application requires a bus switching module, the IC660BSM021 is the only compatible option. Connect the BSM to terminals 9 and 10.

Terminal Assignments and Wiring

The IC660BBA105 has 32 terminals organized for specific functions.

Power Connections

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

• Terminals 9 and 10: Bus Switching Module connection

Output Connections
Terminals 11 through 32 connect to the self-powered inputs for the six analog outputs. Each output pair uses adjacent terminals.

Serial Bus Wiring
Recommended wire size for serial bus is AWG #12 (3.3 mm²) for single wire connections. When you need two wires in one terminal, use AWG #14 (2.1 mm² each). Minimum acceptable wire size for serial bus is AWG #22 (0.36 mm²).

Field Signal Wiring
For output signal wires, the recommended size is AWG #14 (2.1 mm²). Minimum recommended size is AWG #20 (0.54 mm²).

Status Indicators and Physical Dimensions

The front panel of the IC660BBA105 includes two LED indicators. The Unit OK LED shows the module has power and is functioning. The I/O Enabled LED indicates the outputs are active.

Physical Dimensions

• Height: 8.83 inches (22.44 cm)

• Width: 3.50 inches (8.89 cm)

• Depth: 3.94 inches (10.00 cm)

Mounting Requirements
Mount the IC660BBA105 on a panel using the provided mounting holes. Use 8-32 size screws for secure attachment. Connect the module to ground using star washers. Install the block in any enclosure that provides adequate airflow and protects against industrial contaminants. The ambient operating temperature should not exceed 60 degrees Celsius.

Installation Guidelines

First, mount the IC660BBA105 securely to the panel. Next, connect the 115 VAC or 125 VDC power source to terminals 6 and 7. Then, wire your field devices to terminals 11 through 32 for the six outputs. For serial bus communication, use the recommended AWG #12 or #14 wires.

After completing all wiring, connect a handheld programmer to the monitoring port. Configure each output channel individually using the handheld monitor. Set the output hold behavior for each channel. Choose either last output state or a default safe state. Finally, enable the Genius bus communication and verify the Unit OK LED illuminates.
