The ARU208(PZA)
Specially designed with flexibility and functionality in mind. Various ways to switch the 8 relays are provided, including the integrated web interface, optional PA consoles, and analog contact triggering, making the ARU208 AUDAC one of the most intelligent and innovative relay modules. This ingenious device allows for switching between audio sources, signal routing, and even custom automation setups. The two-pole relays allow switching of balanced mono and unbalanced stereo signals. Normally open and normally closed contacts are also provided. A wide variety of signals can be switched, ranging from line-level audio signals to amplified speaker signals (low impedance or 100 V) and voltage distribution (low voltage up to 240 V AC mains voltage distribution).
Relay triggering is possible via dry contact inputs, which can be used to trigger relays via external devices or actuators. Dry contacts have priority over digital functions/triggers. Typical applications include activation via external buttons, switches, or alarm contacts. Thanks to its modular nature, the ARU208 is perfectly suited for small domestic or retail applications, as well as for large installations. Integration of numerous ARU20x units into a system is possible thanks to RS485, which allows daisy-chaining of multiple units.
The ARU208 features an RS485 input and output connector, allowing for even more convenient connections. TCP/IP control capabilities allow the ARU20x to be integrated into any Ethernet network. The built-in web browser running an HTML5 interface enables the most flexible and comprehensive 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 capabilities, while the rear is equipped with a spring-loaded mounting mechanism that allows easy mounting on widely available standard DIN rails. This makes it possible to easily integrate it into any electrical cabinet where it can be powered by the optional PSD24x power supply.
