digital relay unit – 4 relays
The ARU104MK2 is a special designed flexible relay module, consisting of 4 relays. These can be used for switching between two different input signals. In the most common situations, a background music signal and a priority signal are applied.
In combination with the APM paging consoles, it offers a simple and versatile paging solution that can be applied to all types of systems. It has full priority and can be switched between 100V and standard low impedance speaker signals as well as line level signals.
There’s the possibility to connect multiple units in cascade which offers a wide range of possibilities for all kinds of applications.
They are suitable to be mounted on a standard DIN rail, providing connection strips for the in- and output signals.
