Casambi CBU-ASR interface 2 x 0-10V

This Casambi interface generates two 0-10V signals that can be controlled separately as standard, but that together in the app can also control a perfectly tunable white system. Similar to other 0-10V units, this interface also has a relay output that goes high when dimmed.

There is also a SENSOR input on this device that is separate from the operation of as described above. For example, you can connect a twilight switch from another brand that has a switching contact to this input. You then feed that switching contact with the + of the supply voltage and you offer the switching wire to the SENSOR input. If you are going to use this input, see the SETUP tab to learn how to configure this section. If you want to use an auxiliary relay, you will find it in the selection list.


Casambi CBU-ASR enters the Casambi lamp field as follows;

The connection voltage of CBU-ASR is 12VDC or 24VDC, whereby the output of the relay contact assumes the same voltage as the supply voltage selected by you. You may not connect more than 1 driver per 0-10V output.

A frequently asked question is about the 0-10V output. At 0% dimming value, this is 0 Volt. Many drivers, however, do not switch the LEDs off completely at 0 Volt and that is what the auxiliary output is for. With that contact (which is designed as a transistor output) you can release a relay at 0% dimming value. The relay (which must be equipped with a extinguishing diode over the coil) can in turn supply your drivers with 230V. You could also choose to select a solid-state relay. We have various relays in our CASAMBI ACCESSORIES.

There is also a SENSOR input on this unit. For example, you can connect a twilight switch of another brand that has a switching contact to this input. You supply this switching contact with the + of the supply voltage and the switching wire is offered to the SENSOR input. You can set the SENSOR in the Casambi app. (see tab on the right; SETUP)

connection diagram Casambi CBU-ASR

Here you can see the available profiles of CBU-ASR. You can change the profile just before adding the interface to your network. If you have already added this interface to your network and you want to change the profile, you must first disconnect it. Changing profiles has direct consequences for the display and operation in the lamp field, which is why we have shown some screenshots;

Below we show you how to set up a movement sensor Casambi CBU-ASR. In the field SENSORS you will find the sensor;


You will now see that the sensor is not in use, and since you want to program it, click on that line;
