Emergency stop switch wiring

The emergency stop switch is connected to the PLC with an external cable and the Connector Conversion Box.

• Use the emergency stop switch signal as control signals of external device power ON/OFF. Do not use it as the input

signal of external device.

When turning ON/OFF the external device power, set the load up to 24VDC/1A (contact specification).

• For the emergency stop circuit, be sure to configurate the circuit outside the PLC.

(The example of when the connector conversion box is used)

• For the emergency stop SW, the b contact type is used.

• When the Handy GOT is removed from the connector conversion box, the emergency switch goes off, and the Handy

GOT goes into the same state as when the switch is pressed.

• The connector conversion box (GT16H-CNB-42S) and CC-Link interface unit (GT11H-CCL) contain a parallel circuit

to avoid emergency stop while the Handy GOT is being removed.

• CC-Link interface unit (GT11H-CCL) does not require the wiring to the parallel circuit.

• The connector conversion box (GT16H-CNB-42S) requires the wiring to the parallel circuit.

• The connector conversion box (GT11H-CNB-37S or GT16H-CNB-37S) does not include the parallel circuit. To be

prepared by the user.
