Introducing the Absolute Encoder Module

Chapter 2

2Ć2

You can use the absolute encoder module with any Allen-Bradley

programmable controller that uses block-transfer programming in both

local and remote 1771 I/O systems. Processors that are compatible with

the module include:

Mini PLC-2 (cat. no. 1772-LN3)

PLC-2/20 (cat. no. 1772-LP1, -LP2)

PLC-2/30 (cat. no. 1772-LP3)

PLC-3 (cat. no. 1775-L1, -L2)

Mini-PLC-2/15 (cat. no. 1772-LV)

Mini-PLC-2/05 (cat. no. 1772-LS, -LSP)

You can use Allen-Bradley absolute encoders that use up to 12 bits with

the absolute encoder module. Allen-Bradley encoders with the following

bulletin numbers are compatible with the absolute encoder module:

Bulletin 845A

Bulletin 845B

Bulletin 845C

The module is also compatible with absolute encoders that have the

following specifications:

single-ended or differential encoder output signals

TTL-compatibility (output drivers)

capability of sinking 11mA (single-ended) or 18mA (differential) per

channel

BCD, natural binary, or standard Gray code format

You can select the state in which the outputs will be if the module loses

input power. A configuration plug on the right printed-circuit board

allows the outputs to:

turn off

remain in their state at loss of input power
