====== 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** ;;# Unipi 1.1 ;;# 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. /* Unipi 1.1 */ ===== Unipi 1.1 ===== /* zapojení RO */ {{page>:en:hw:connection-of-ro-11-hidden}} /* Parametry RO */ {{page>:en:hw:technical-parameters-ro-11-hidden}} /* Unipi 1.1 Lite */ ===== Unipi 1.1 Lite ===== /* zapojení RO */ {{page>:en:hw:connection-of-ro-lite-hidden}} /* Parametry RO */ {{page>:en:hw:technical-parameters-ro-lite-hidden}}
