4-3 I/O Wiring
4-3-1 Wiring to the Screwless Clamping Terminal Block
All of the GRT1-series Slice I/O Units can be wired with screwless clamp ter-
minal blocks, which do not require screws to be tightened. When connecting a
sensor or an external device, always crimp pin terminals to the cable of the
sensor or device. There are two types of pin terminals: one-pin terminals and
two-pin terminals. By using two-pin terminals, wiring can be performed with-
out using a GRT1-PC8(-1) I/O Power Connection Unit when connecting a 2-
wire sensor to a GRT1-ID8(-1). When using a GRT1-OD8(-1), wiring can also
be performed without using a GRT1-PC8(-1) I/O Power Connection Unit.
The following table shows the compatible pin terminals.
One-pin Terminals
Two-pin Terminals
Pin Terminal Length Use pin terminals with a pin (conductor) length of 9 to 11 mm.
Wiring to a Clamping Terminal Block
Insertion Fully insert the pin terminal into any terminal hole.
Removal Press the release button above the terminal hole with a slotted precision
screwdriver and pull out the wire.
Note (1) When pressing the release button, press with appropriate force (30 N
max.). If excessive force is used, the terminal block may be damaged.
