WARNING
・ DO NOT connect any circuit other than SELV (DC+ 24V) (Safety Extra Low Voltage) to the
External Input / Output Connector A ③ of the CONTROLLER. This will cause I / O board damage
in the CONTROLLER.
・ Do not supply over voltage or over current into the input / output circuit. Always install a LOAD
(resistor) to the output circuit to eliminate the chance of damage to the CONTROLLER.
CAUTION
Input / Output Connector A ③ do not use Pins No. 9 and No. 22. If pin No. 9 and No. 22 are
connected, the CONTROLLER will be damage.
