GE Fanuc IC660BBA106 Genius Current-Source Analog Input Block
Six-channel isolated 4-20 mA input block with per-channel loop excitation and diagnostics.
01Model Profile
IC660BBA106 connects six 4-20 mA field transmitters to a Genius controller. Each input provides a 24 V current-loop supply and is isolated from the other circuits.
Scaling parameters convert current values into the engineering-unit range required by the control application. Input conversion time is selectable from 16.6 to 400 ms, and each channel can report high alarm, low alarm, underrange, overrange or current below 2 mA.
The block requires later Genius bus controllers IC660CBB902 or IC660CBB903 rather than IC660CBB900/901. An IC660BSM021 can be controlled when redundant bus cabling is used.

03Six Isolated Loops
- Every input carries its own loop-excitation path.
- Channel-to-channel isolation separates all six field loops.
- The BSM circuit is common to input 1 but isolated from the remaining inputs.
04Scaling and Diagnostics
Configuration point
Range, alarm and below-2 mA diagnostics distinguish signal conditions.
Installation check
Controller compatibility must be checked against CBB902/CBB903 generation.
