6. RECOMMENDED CABLE TYPE AND PERMISSIBLE LENGTH
* : For readers, thicker wires are needed if you connect the reader with high current consumption.
7. REVERSE DIODE CONNECTION
If you connect the output device with coil (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 a reverse
diode, the surge voltage will transfer and damage the electronic circuit of the controller.
It is strongly recommended to add a reverse diode between the inductor coils to absorb this surge voltage.
