2.10.3 Common output circuit
There are 3 common outputs: DO1 and DO2 are single-ended, sharing a common power
supply ground terminal; DO3+/DO3- is double-ended, having an isolated 24v power
supply.

Please install flyback diodes (as shown in diagram above) if the output is through a relay
or other inductive load to prevent damage to DO ports.

Power supply is provided by user. Please be aware that reversed power supply
polarity might cause damage to the driver.
When it is an open collector output, max current: 50mA, max supplying voltage: 25V.
Please ensure the switching power supply fulfills the conditions.
If the load is an inductive load such as a relay, please connect a flyback diode in
parallel in reverse. A wrong installation of the flyback diode might cause damage to
the driver.
