GE IC660BBA104 115 VAC / 125 VDC analog combination block

IC660BBA104 combines four current-loop inputs and two current-loop outputs in one 115 VAC / 125 VDC Genius I/O block.

Its input section provides 1 µA resolution, while the output section provides 6 µA resolution and feedback diagnostics.

The IC660BBA104 is suited to Genius architectures requiring both process-variable acquisition and analog command signals in the same field I/O location.

It becomes especially relevant when an existing block develops input alarms, open-wire conditions, output feedback faults or abnormal current-loop behavior.

BBA104 is dedicated to 4–20 mA current-loop I/O, while BBA100 is the broader analog I/O block with voltage and current range selections. The existing field signal type should determine the choice.

Yes. BBA024 provides the corresponding current-loop mixed I/O function for 24/48 VDC block power, whereas BBA104 is the 115 VAC / 125 VDC version.

It combines four measurement channels and two command channels within one Genius field block, which can simplify an existing I/O architecture where both signal directions are required.

Input underrange, overrange, high/low alarms and open-wire detection help isolate input-side issues; output underrange, overrange and feedback-error diagnostics address the output side.

Verify the quantity, destination, required date and the machine/system so the commercial request matches the installed application.

Because it handles both input and output functions, one block-level failure can remove process measurement and control signals at the same field location.
