The ARU108MK2 is an intelligent relay unit featuring eight double pole relays with normal open and normal closed contacts. Control can be done through both digital (RS-485) and analogue (contact) input signals. Thanks to the flexible structure in terms of connectivity and control, the ARU108MK2 can be implemented in a wide variation of applications, adding flexible and intelligent functionality to your audio & video related or any other project.

The signal inputs are capable of handling a wide varity of signals, including line level audio signals, loudspeaker level signals or low voltage power distribution with a maximum voltage up to 100 Volts. The inputs shall be connected to the A and B input terminals implemented using 3-pin screw terminals, whereof A uses normal open (NO) contacts and B uses normal closed (NC) contacts. The switched output comes available on the 2-pin output signal connections. The double-pole construcion also allows switching of balanced / differential signals.

Digital communication with the unit is done using the RS-485 data protocol, which allows the ARU108MK2 to be used in combination with APM1xx paging microphones for application to any existing audio system for switching between background music and prioritary voice announcements. When applying it to any digital audio matrix system such as R2, M2 or MTX series, additional functionality such as the control of monitors, projection screens, lighting, ... and many more can be achieved.

The unit is housed in a DIN-rail mountable enclosure, which allows rack / cabinet implementation with other electrical or control equipment.
