Gateway interface module ARU208

DIN railEthernetRS485

Multi-channel digital relay unit - 8 relays Compatible with AUDAC Touch™ Remote control web interface (HTML5) DIN rail mounting enclosure RS485 & TCP/IP controllable Pre-programmed timed relay triggering Terminal block connection (In- and output) Double pole relays with Normal Open (NO) and Normal Closed (NC) contacts 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.
