4.2.4 REVERSE DIODE CONNECTION
If you connect an inductor (Door Locks or Alarm device) to the output relays, there will be a high surge voltage
created while the inductor is turning on and off. If you do not connect reverse diode, the surge voltage will
transfer and damage to the electronic circuit of the controller. It is strongly recommended to add a reverse diode
between the inductor coils to absorb this surge voltage.
