====== Relay outputs ======
/* Úvodní popis RO na Unipi 1.1 / Lite */
Relay outputs are terminated on terminals labelled by a switch schematic sign and serve for switching two-state devices with alternating or current voltage. The **COM** terminal is common, serving as input for switching voltage. **NO** and **NC** terminals are used as the switching voltage output.
* **NO** - in the default state (no voltage), contacts are **open**
* **NC** - in the default state (no voltage), contacts are **closed**

The state (On/Off) of each relay is indicated by a LED with a corresponding label. Overload and overvoltage protection should be provided externally by a circuit breaker (ideally one for each output). Nominal current and circuit breaker type should be selected according to the load and its characteristics concerning the maximum current on the output.
**Warning:** \\
If an inductive load is connected (e.g., electric motors, relay coils, contactors, or even the cables in extensive electric installations), it is necessary to protect the relay outputs with a corresponding external element (e.g., varistor, RC circuit or a suitable diode).
If a capacitive load is connected (e.g., power sources of LED lights), it is necessary to protect the relay contacts against inrush current by connecting a corresponding thermistor to the relay's output.
