(1) Details of External Input / Output Connector A Signals
WARNING
・ DO NOT connect any circuit other than SELV (DC+24V) (Safety Extra Low Voltage) to the External
Input / Output Connector A 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
External Input / Output Connector A DOES NOT use Pins No. 9 and No. 22. If pin No. 9 and No. 22
are connected, the CONTROLLER will be damage.
