1. The DO+ pin provides 12V output voltage, and the max. load is 50mA.
2. The max. voltage for DO- pins is 80VDC (External power).
In order to control AC devices, the above diagram can be taken in consideration. The diagram
uses a relay to control the ON/OFF condition of the AC device.
3. An external relay can be triggered by using DO+ or by an external power source, depending
on the type of relay you use.
4. In case of using an individual relay (instead of using a relay module), for protection against
voltage or current spikes, a transient voltage suppression diode must be connected in parallel
with the inductive load.
