Wiring
When the PC controls an operation such as the clockwise and counterclockwise
operation of a motor, provide an external interlock such as the one shown below
to prevent both the forward and reverse outputs from turning ON at the same
time.
This circuit prevents outputs MC1 and MC2 from ever both being ON at the same
time. Even if the PC is programmed improperly or malfunctions, the motor is pro-
tected.
The 24 VDC output of the CPU and Expansion I/O Power Supply may be used to
power other devices. The output current of these supplies is limited to 0.3 A. A
separate power supply must be provided if the devices being powered require a
higher current.
When two-wire sensors, such as photoelectric sensors, proximity sensors, or
limit switches with LEDs, are connected to the PC as input devices, the input bit
may be turned ON erroneously by leakage current. In order to prevent this, con-
nect 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 value and rating for the
bleeder resistor using the following formulas.
