Multi Extension Air

The Loxone Multi Extension Air features 8 dry contact latching relay outputs, 12 digital inputs, a 1-wire interface and 4 PWM outputs to control RGBW LEDs.

The connection to the Miniserver is via the Loxone Air wireless interface.

Mounting

The Multi Extension Air is installed on a DIN rail in a suitable enclosure.

For thermal reasons the total load rating must not exceed 48A (IEC) or 45A (UL).
The Multi Extension Air uses latching relays. Relays of this type can remain in the ON position even when the device is disconnected from power.

Commissioning

In delivery state, pairing mode will be active after the power supply has been established. This is indicated by the status LED flashing red/green/orange.

Then follow the pairing procedure

To activate the pairing mode manually, hold down the pairing button for at least 5 seconds after establishing power supply.


Note

The digital inputs can also be used as frequency meters. This allows for pulse counters such as electricity or gas meters to be connected. Since the counted pulses are only transmitted once per minute, the Multi Extension is not suitable for the connection of pulse output wind sensors.

The PWM output can be set to Standard, Smart Actuator (for dimming LED lighting) or PWM control signal in the actuator type properties. The analogue value of the outputs (0-100%) is pulse width modulated.

The same properties, functions and notes that apply to the 1-Wire Extension also apply to the 1-Wire interface of the Multi Extension.

Safety shutdown: If the CPU temperature rises above 80°C / 176°F, the digital outputs are switched off. As soon as the temperature has dropped below 65°C / 149°F, the outputs are reactivated. The temperature value is updated on restart and when the temperature changes by 5°C / 9°F.
