GE Fanuc IC660BBA106 Current Source Analog Input Block

GE Fanuc IC660BBA106 Genius Current Source Analog Input Block

The GE Fanuc IC660BBA106 is a Genius series current-source analog input block designed to acquire analog current signals and transmit digital data to a connected controller. This block provides six analog input channels and is intended for use in industrial control and automation environments requiring monitored current-loop inputs.

Six-Channel Current Input Architecture

• Six analog current input channels
• Supports 4 mA to 20 mA and 0 mA to 25 mA input ranges
• Each channel provides a 24 V current loop power supply
• Individually isolated input points

Signal Conversion and Data Handling

When powered, the IC660BBA106 converts analog current signals into digital values using voltage-to-frequency conversion before transmitting data to the CPU. Conversion times are programmable from 16 ms to 400 ms, allowing configuration of input resolution and noise rejection based on application requirements.

Industrial Control Applications

• Analog signal acquisition from field transmitters
• Process monitoring using 4–20 mA current loops
• Integration within GE Fanuc Genius I/O systems
