Connection Diagrams for Allen Bradley Encoders

Figures E.1 through Figure E.3
Allen-Bradley encoders to the absolute encoder module:
Figure E.1 shows you how to connect a Bulletin 845A encoder, 0 to
359-count, 10-bit, BCD, single-ended output encoder.
Figure E.2 shows you how to connect a Bulletin 845A encoder, 0 to
255-count, 8-bit, Standard Gray, single-ended output encoder.
Figure E.3 shows you the connections for a Bulletin 845C encoder, 0 to
359-count, 10-bit, BCD, single-ended output, latching encoder.
Follow these guidelines:
Make the wht/orn wire (pin V) an open connection.
The encoder counts up in a counterclockwise direction if you make the
wht/yel wire (pinQ) an open connection or if you connect it to +5V; if
you connect it to ground, the encoder counts up in a clockwise
direction.
Signal common wht/blk (pin W) and ground blk (pin X) are internally
connected on the encoder.
Jumper the unused most-significant-bit input terminals.
