allowable current to 1 A or greater. If Reed switches with smaller allowable cur-
rents are used, the contacts may fuse due to surge currents.
When two-wire sensors, such as photoelectric sensors, proximity sensors, or
limit switches with LEDs, are used, the input bit may be turned ON erroneously
by leakage current. In order to prevent this, connect a bleeder resistor across the
input as shown below.
If the leakage current is less than 1.3 mA, there should be no problem. If the leak-
age current is greater than 1.3 mA, determine the resistance (R) and power rat-
ing (W) for the bleeder resistor using the following formulas.
