Rockwell Automation 1395 Encoder Driver Module - Manual (Page 3)

Encoder Driver Module
Instructions

Press Speed Pick–Up signals are connected as follows:
1. Only the channel A input is used, the HI signal is connected to AI2
channel (TB1–6).
2. Module outputs for the encoder 2 channel A output only are
connected directly to the RTP digital ref adapter PC Board
terminals.
Quadrature Encoder/ Multiple Inputs – Figure 2 depicts one quadrature
encoder (with 0 to 12 volt, 15 milliampere outputs) that will be used to
provide digital reference signals for four different drive inputs. Note that
in this application it is necessary to both provide burden resistors for the
outputs of the 12 volt encoder as well as voltage dividers to bring the input
signal level to a maximum of 5 volts.
