Audac - AUR04 - Relay Unit
2007
 

Features:

  • Simple and fast set-up
  • Mounted on DIN-rail
  • Status-leds to facilitate control
  • Jumpers for routing

Applications:

  • Thanks to the build-in micro controller, 4 switching relays can be configured for any switching application
  • Must be combined with the AUDAC APM paging consoles
  • Possible to connect multiple units or combine with other ARU-versions

Where there is a need for zonal announcements and contact controls in paging or evacuation systems, the ARU-4 is the ideal solution. This relay unit is fitted with 4 switching relays which can be configured for any switching application by means of the built-in micro controller. This unit must be combined with the AUDAC APM paging consoles, giving a simple and fast set-up. The unit is standard mounted on DIN-rail with simple connectors for signal and loudspeaker level. Due to this mounting, a cable connector board is immediately created when building 19 “ racks. The input connectors have been paired so that switchable signals can be immediately connected (e.g. paging and music signal). Through addressing, it is possible to connect multiple units in series or parallel or to combine the unit with other ARU-versions.

This offers a large range of possibilities for complex systems (zone switching, 24 V charges, alarms, messages,…). All the relays are fitted standard with “status leds” enabling operation conditions to be easily controlled. Furthermore, the design has been constructed insuch a way that those relays at rest are energised whereby the call is always switched through in the event of misfunction. As an additional advantage, the ARU-4 contains “jumpers” which allows routing of the input signal. A small switching matrix can thus be constructed as a function of the intended application. The ARU-4 works on a 24 V DC power supply and the relays are activated according to the principle of grounding (common line). Through the RS485 data bus, communication with the APM paging tables or other control equipment is established (e.g. Crestron, AMX,…).

Specs:

  • Number of Relays 4
  • Dimensions 113 x 210 mm
  • Weight 0.55 kg
  • Height 100 mm
  • Standard Databus RS485
  • Fire hazard class VO (UL94)
