External Device Connection Examples
Refer to the following information when connecting output devices.
!WARNING Serious injury may possibly occur due to breakdown of safety outputs or test
outputs. Do not connect loads beyond the rated values to the safety outputs
and test outputs.
!WARNING Serious injury may possibly occur due to loss of required safety functions.
Wire the G9SP-series Controller properly so that the 24VDC line does NOT
touch the outputs accidentally or unintentionally.
!WARNING Serious injury may possibly occur due to loss of required safety functions.
Ground the 0V line of the power supply for external output devices so that the
devices do NOT turn ON when the safety output line or the test output line is
grounded.
!WARNING Serious injury may possibly occur due to loss of required safety functions. Use
appropriate components or devices according to the requirements given in the
following table.
Precautions for Correct Use
• Be sure to separate I/O cables from high-voltage and power lines.
• The cable length from an output terminal to the output device must be
100 m or less.

Control device Requirements
Contactor Use a contactor with a forcibly guided mechanism. For feed-
back signals to detect contactor failure, use a device with NC
contacts. For feedback, use a device with NC contacts capa-
ble of switching micro-loads of 6 mA at 24 VDC.
Other control device Verify whether the device is appropriate for the required safety
category.
