(b) Digital Output Interface Circuit
(IO2)
:
When using an external power supply, pay attention to the polarity of the power supply, reverse
polarity will cause damage to the driver. The digital output is an Open Collector method, the
maximum external voltage is limited to 24V, and the maximum current is 10mA. In terms of load,
when using a relay or other inductive loads, it is necessary to add a diode in parallel with the inductive
load, if the polarity of the diode is reversed it will cause damage to the driver.
