Product Description

The IC660BBA106 is a Current-source Analog Input Block with six channels of GE Fanuc series 90-30 PLCs. The required power supply for this block is 115VAC or 125VDC. It has six current inputs of 4mA to 20mA. Each one provides a 24V current loop power supply with accuracy as precise as 0.1% and is isolated. It also has a BSM circuit electrically common to input 1 but is isolated from the others.

When power is provided to the block, input channels translate analog current to digital value as whole integers using voltage to frequency converters; after that, they send it to CPU. Input conversion time can be selected to provide the appropriate combination of noise rejection and input resolution. Conversion times are programmable from 16mS to 400mS. Resolution increases as the conversion time is lengthened. Input resolution is 1μA for 200mS conversion time. Upper and lower alarm limits can be programmed for each input circuit. If either limit is exceeded, the block indicates a fault and sends a message to the handheld mnitor, which is required for configuration and control of the IC660BBA106 Current-source Analog Input Block. In each bus scan, the block broadcasts 12 bytes of input data. Each input consists of two bytes of data.

The IC660BBA106 has 32 terminals. Power source connects to terminals 6 and 7. Input cables connect to the self-powered inputs 10 to 32. The bus switching module connects to terminals 8-9.

The IC660BBA106 input block from GE Fanuc is an analog input block and a member of the Genius I-O series. It has 6 input channels that are current sourcing inputs and that can all operate within a current range of 4 to 20 milliamps. The IC660BBA106 input block can operate with either a 115 Volts AC rated power supply or with a 125 Volts DC rated power supply. Its operating voltage ranges are 93 to 132 Volts AC and 105 to 145 Volts DC. This analog input block supports channel to channel isolation rated at 1500 Volts RMS. Its input impedance rating is 100 Ohms and it dissipates approximately 12 Watts of heat during normal operation. The ambient operating temperature range for the normal operation of the IC660BBA106 analog input block is from 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit.


The GE Fanuc IC660BBA106 Genius I-O analog input block contains fault-reporting features. These features scan and diagnose the input block automatically and they warn the operators about errors in the system promptly so that the operators can address the errors as quickly as possible to prevent severe or permanent component damage or user injury. The fault-reporting features of the IC660BBA106 analog input block include several alarms and reporting for overrange power levels and underrange power levels. The users can configure and control the IC660BBA106 input block with a compatible handheld monitor or HHM. The handheld monitor is also the device that receives the alarms and alerts that the block’s fault-reporting features generate.

Customer Questions and Answers

  • Question:  What is an IC660BBA106?  Answer:  The IC660BBA106 is an 115 VAC/125 VDC Current-Source Analog Input Block of the GE Fanuc Genius I/O Series. This block is used to interface a controller to devices that provide 4-20mA analog signals.
  • Question:  What is the difference between IC660BBA106 and IC660BBA026?  Answer:  The only difference between these blocks is their power supply.
  • Question:  How many inputs are on this block?  Answer:  There are 6 inputs.
  • Question:  What will I need to test this block?  Answer:  You will need a slot rack, a power supply, a CPU, and IC693BEM331. You will also need a Hand Held Monitor. 
  • Question:  When using the HHM for configuration of IC660BBA106, at what baud rate should you be communicating?  Answer:  153.6K Standard
  • Question:  After configuration what should happen?  Answer:  The Enabled LED light should come on letting you know the block is enabled (this should happen when the CPU is in run mode).
  • Question:  What should you probe on this block when testing it?  Answer:  The "in" and "common" of each channel. 
  • Question:  How might I know there is something wrong with my IC660BBA106?  Answer:  If you power it up and you do not get any lights or if your inputs are not giving you proper readings then there could be something wrong with your block.
