exceeding the switching capacity to Output Units. Doing so may result in dam-
age or destruction of the I/O Unit or result in fire.
When two-wire sensors, such as photoelectric sensors, proximity sensors, or
limit switches with LEDs, are used, the input bit may be turned ON errone-
ously by leakage current. If the leakage current exceeds 1.3 mA, insert a
bleeder resistor in the circuit to reduce the input impedance, as shown in the
following diagram.
