Stand-Alone Relay Module REL04SA - Qbus

This module with 4 outputs and 5 inputs is the base of the Qbus Stand-Alone range and functions both autonomously - so without controller, without external power supply and without any configuration - but can also be connected to a controller to become part of a full-fleged Qbus installation.
Input 1 to 4 control respectively output 1 to 4. Input 5 (A) is a scene-input which executes an ALL off scene when pushing for 0,7 seconds, or a panic scene, all outputs on when pushing the button for 3 seconds.

The REL04SA contains 4 outputs of each max 16A to control lighting, shutters, power plugs…
For shutter/blind/curtain control, the REL04SA needs to be set in “Shutter mode”.
For heavy inductive loads (many fluorescente lights) with a high capacity or bipolar application, contactors need to be added.
It is also possible to configure a REL04SA module via a Qbus controller and then take the controller away. This way, the relay contacts can be configured with a delay ON, delay OFF and TIME OFF function. Keep in mind that besids the TIME-OFF function, no other timers are possible in Stand-Alone mode. Using the controller, the inputs can be set as Normal Open, Normal Closed, Pushbutton.
