Wiring Methods
1,2,3...
Note When using a reed switch as the input contact for an AC Input Unit, use a
switch with an allowable current of 1 A or greater. If Reed switches with
smaller allowable currents are used, the contacts may fuse due to surge cur-
rents.
When using a two-wire sensor with a 12-V DC or 24-V DC input device, check
that the following conditions have been met. Failure to meet these conditions
may result in operating errors.
1. Relation between voltage when the PLC is ON and the sensor residual
2. Relation between voltage when the PLC is ON and sensor control output
3. Relation between current when the PLC is OFF and sensor leakage cur-
