IC600BF923 can be installed in a Series Six I/O rack or in an I/O slot of a Series Six Plus CPU rack. The backplane DIP switches behind the slot must reserve 32 consecutive bits in the CPU Output Status Table before the module is inserted.

JP1 selects the response. Position 1-2 turns all outputs off, while position 2-3 retains the last commanded states until valid data returns or user power is removed. Applying user power initializes every output off.

JP2 selects normal or inverted data handling. In normal mode, a logical 1 in the Output Status Table turns the active-low output on. When IC600BF923 drives a high-density input module, both modules should use the same inversion mode so the transferred bit values are not reversed.

Loads may use supplies between 10 and 50 VDC when all supplies share one common negative point. Connect terminal 33 to the lowest voltage present and, for suppression of inductive loads, connect CLP terminal 34 to the highest positive supply voltage used.

The GE Fanuc ordering note identifies equipment with the same IC600BF923 catalog number and a higher alpha suffix as a direct replacement for the same catalog number with a lower alpha suffix. The complete suffix on the installed nameplate should still be recorded before replacement.
