Digital I/O Units Section 4-6
When connecting 2-wire sensors, wire using the GRT1-PC8-1 I/O Power
Connection Unit as shown in the following figure. A single I/O Power Connec-
tion Unit can be connected to up to two GRT1-ID8 Units.
If you are connecting 2-wire sensors, you can use dual-insert rod terminals to
eliminate the need for a Power Connection Unit.
Note Wire colors in parentheses are the previous JIS colors for photoelectric and
proximity sensors.

tion Unit as shown in the following figure.
