GE IC660BBA106 six-channel current-loop input block

IC660BBA106 provides six analog current inputs for devices delivering 4–20 mA signals.

Conversion time can be selected from 16.6 ms to 400 ms, allowing the installation to balance response speed, resolution and noise rejection.

The IC660BBA106 is suited to Genius field networks where transmitters and other 4–20 mA devices must be monitored through multiple analog channels.

It may be searched for when a channel reports an abnormal value, an open-wire condition, an alarm-limit violation or when an aging input block begins affecting process supervision.

BBA106 is a six-channel analog input block, whereas BBA105 provides six analog outputs. They serve opposite signal directions and cannot be substituted solely by matching the channel count.

Yes. BBA026 is the 24/48 VDC counterpart, while BBA106 uses 115 VAC / 125 VDC block power.

The selectable 16.6–400 ms range allows the application to balance acquisition speed with signal quality and resolution requirements.

Check block power, Genius communication, common wiring conditions and loop excitation before treating all six field devices as independent failures.

The input excitation supports specified loop-impedance limits. The field transmitter and wiring should remain within the applicable range.

Provide the exact part number, quantity, destination, required date and machine/system. For engineering review, the installed power type and current-loop arrangement are also useful.
