AUDAC ARU204 Accessories - 4 network relay unit - M2/R2/MTX
Accessories - 4 Mains Relay Unit - M2/R2/MTX
The ARU204 is specially designed with flexibility and functionality in mind. Various switching modes of the 4 relays are available, including the integrated web interface, optional call stations or manual triggering of the analog contact, making these the most intelligent and innovative relay modules.
With this ingenious device, you can manage switching between audio sources, signal routing and even custom automation configurations. Bipolar relays allow switching between balanced mono or unbalanced stereo signals. Normally open and normally closed contacts are also provided.
Thanks to its modular nature, the ARU204 is ideal for small domestic or commercial applications as well as large installations. There is no limit to the number of ARUs connected to a system. The ARU204 can be controlled over an existing Ethernet network via an integrated HTML5 web server, allowing full control via any connected PC, laptop or intelligent device. Two RJ45 connectors are provided to allow you to chain multiple ARU modules.
The front of the black ABS case gives a brief overview of its connection possibilities, while the rear is equipped with a spring mechanism for easy mounting on standard DIN rails. In this way, it can be easily integrated into any control cabinet.
