Introduction
Multi channel digital relay units
The ARU20x series are multi channel digital relay units which are especially designed with
flexibility and functionality in mind. Various ways of switching the relays are provided, including
an integrated web interface, optional paging consoles and analog contact triggering making
the ARU20x 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.
Thanks to its modular nature, the ARU20x is perfectly suitable for small home or retail
applications as well as big installations. There is no limit to the amount of ARU’s connected to
one system. The TCP/IP functionality allows controlling the ARU20x over an existing ethernet
network through an integrated HTML5 webserver, achieving full control via any connected
PC, laptop or smart device. An RS485 control port allows them for being integrated with any
matrix or other controlling system.
They are housed in a DIN rail mountable enclosure, guaranteeing an easy and clean installation
and integration in electrical cabinets. 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.
