3.2 CONTROL SIGNAL WIRING
ZLAC8015 series driver provides 2 photoelectric isolation programmable input
interfaces, compatible with NPN wiring and PNP wiring.
2-channel (IN1-IN2) programmable input signal is isolated from the external control
interface by an optocoupler. The driver is compatible with common cathode and
common anode connections, as shown in the following Figure 2. In order to ensure the
reliable conduction of the optocoupler inside the driver, the drive current provided by
the controller must be at least 10mA.
The level pulse width of IN1-IN2 input needs to be bigger than 10ms, otherwise the
driver may not respond normally. The IN1-IN2 timing diagram is shown in Figure 3.

Fig.3 Control signal interface wiring diagram
Note: The default input voltage of the control signal is 5V. For other voltages,
current limiting resistors must be added, for example: 12V, external 1K 1 / 2W resistor;
24V, external 2K 1 / 2W resistor.
After the driver is powered on, IN1-IN2 defaults to the unspecified state. At this time,
the input signal is invalid. User could configure IN1-IN2 input functions through bus
