The ARU208 is specially designed with flexibility and functionality in mind. Various ways of switching the 8 relays are provided, these include the integrated web interface, optional paging consoles and analogue contact triggering making the ARU208 AUDAC’s smartest and most innovative relay modules.

With this ingenious device, switching between audio sources, signal routing, and even customized automation setups are obtainable. The bipolar relays allow switching of balanced mono signals as well as unbalanced stereo signals. Normal open and normal closed contacts are provided as well. A wide variation of signals can be switched, ranging from line-level audio signals to amplified loudspeakers signals (Low impedance or 100V) and voltage distribution (low voltage up to 240 V AC mains voltage distribution).

Possibility for triggering relays through dry contact inputs, which can be used for triggering relays through external devices or actuators. Dry contacts priority over the digital functions/triggers. Typical applications are activations by external buttons, switches or alarm contacts.

Thanks to its modular nature, the ARU208 is perfectly suitable for small home or retail applications as well as big installations. Integration of numerous ARU20x units in one system is possible due to the RS485 which allows daisy-chaining of multiple units. The ARU208 features an RS485 in and output connector, allowing even more convenient connections. The TCP/IP control possibilities allow integration of the ARU20x’s in any ethernet network. The integrated web-browser running an HTML5 interface allows the most flexible and complete operation while the freely available command set allows integration with any TCP/IP based control or automation system.

The front of the black ABS housing provides a brief overview of its connection possibilities, while the back is equipped with a spring mount mechanism allowing easy mounting on widely available standard DIN rails. This way it’s possible to easily integrate it in any electrical cabinet where it can be powered using the optional PSD24x power supply.

Great value for the money, nice to have on-hand
Style: C20 Parts * 19pcs
This set is great and is an affordable way to keep my eufy Omni C20 Robot Vacuum ready to perform. I run my vacuum in about 500 sq feet of my home at least twice a day. Having all the consumable pieces I need (minus the soap for cleaning the floor and the actual water to fill the tank) on-hand makes machine maintenance easy to do. These pieces are easy to change out, too, and the installation was easy as well. I don't have great hand strength but nothing was too hard for me to change myself.

Bad fit
Style: C20 Parts * 19pcs
The dust bags do not fit properly. You can get the base to acknowledge them if you place them just right, but any little movement can move them out of place. I have to constantly reseat them because the base thinks there is no bag. The stock bags do not have this problem. Edit: It has gotten to the point where it is constantly flipping between registering and not registering the bag. Changing to 1 star because they are unusable. If I'm not there to fix it, the task fails every time.
