WARNING
・
DO NOT connect any circuit other than SELV ( DC+24V) (Safety Extra Low Voltage) to the
External Input / Output Connector B
④
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.
