GE IC660BBA105 115 VAC / 125 VDC analog output block

The IC660BBA105 provides six independent analog output circuits for devices accepting 4–20 mA signals.

Outputs support 0–24 mA overrange capacity and provide underrange, overrange and feedback-error diagnostics.

The IC660BBA105 is appropriate where a Genius network must deliver multiple 4–20 mA control signals to field devices such as current-operated actuators and process-control equipment.

Engineers commonly look for this model when an output channel becomes stuck, loses feedback, falls outside its expected range or when the existing block no longer maintains reliable analog control.

BBA105 is a six-output block, while BBA104 combines four inputs with two outputs. The replacement must match the actual field I/O architecture.

Yes. BBA025 is the 24/48 VDC counterpart of the 115 VAC / 125 VDC BBA105. The signal function is similar, but the block-power requirement differs.

Check the configured output value, field load, wiring, output range and feedback condition. The block can report underrange, overrange and feedback errors.

No. The six output circuits are electrically common to each other and to the BSM output, so the existing field design must be preserved.

The specified current application supports loads from 0 to 850 Ω. Confirming the field load helps prevent an apparently correct replacement from behaving incorrectly after installation.

A failed analog command can affect valves, actuators or other current-controlled devices, potentially interrupting process control.
