3. If preferred, connect the DI/DO or audio output wires to the terminal connectors.
3-1. The DO+ pin provides a 3.3V output, and the max. load is 50mA.
3-2. The max. voltage for DO- pins is 30VDC (External power).
In order to control AC devices, the following diagram can be taken into consideration.
This diagram uses a relay to control the ON/OFF condition of the AC device.
3-3. An external relay can be triggered by using the DO+ or by an external power
source, depending on the type of relay you use.
3-4. 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.
