Digital I/O Units
Section 4-6
If the Unit connected on the left needs to be isolated, wire using the GRT1-
PD8-1 I/O Power Feed Unit. When using the GRT1-PD8-1 I/O Power Feed
Unit, however, a maximum of seven sensors can be connected, as shown in
the following figure.
When connecting 2-wire sensors, wire using the GRT1-PC8 I/O Power Con-
nection Unit as shown in the following figure. A single Power Supply Unit can
be connected to up to two GRT1-ID8-1 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.
