Connection Diagrams for AllenĆBradley Encoders

Figures E.1 through Figure E.3 show you how to connect several

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.
