Connector Terminals
Section 5-2
Terminal Arrangement and Wiring Method
Note
In accordance with the changes in the standards for photoelectric sensors
and proximity sensors, wire colors have been changed. Colors in parentheses
are the old wire colors.
I/O Allocations
Provided that the words of the Connector Terminal with 32 transistor inputs
and 32 transistor outputs allocated as input and output Slaves to the Master
Unit are m and n, the pin numbers of the MIL connector correspond to the fol-
lowing word and bit allocations.
Compatible External Input
Devices and Cables
The Connector Terminals with 32 inputs connect to external devices over one
of the following method.
SRT2-MD32ML
