Isolated Digital Input Circuits
Input accepts voltages up to 24V, with input resistors of 8.2 kΩ, with connections
between outside signals as shown.
h Isolated Digital Output Circuits
Each isolation digital output channel adopts a MOSFET transistor, capable of
driving peak current up to 250mA (sustained current up to 100 mA) with voltage
ranges from 5V to 35V.
The VDD pin is connected in serial with a flywheel diode protecting the driver
during inductance loading, such as relay, motor, or solenoid, wherein the VDD
must connect to external power to form a flywheel current loop.
