Relay-control Signals

Controlling and Signaling Using NEXUS

The XRI relay-interface board is available for reading, generating, and distributing relay-control signals. Depending on configuration the board features galvanically isolated input and switched relay contacts.
Input and relay functions are pre-programmed with regard to the specific application. For example, the following applications can be implemented using the XRI boards:

• Signalling and remote-start distribution via NEXUS
  
• Switching of pre-determined crosspoints using dedicated keys
• Crosspoint-status indication via lamps
  
• Indication of NEXUS system messages via LEDs

Serial Controller

The XCI board is available for connecting or controlling external components. XCI boards also have an application-specific configuration. The board incorporates a dedicated processor and four independent ports to meet even the most complex requirements.
The board is available with various port configurations, for example, RS 232, RS 422, or Ethernet, and supports various protocols.
Suggesting applications include:

• Controlling external machines from an AURUS or CANTUS mixing-console system
• Controlling the NEXUS using external controllers or sequencers
• Interfacing to intercom systems made by SALZBRENNER STAGETEC MEDIAGROUP
• Connecting NEXUS control panels
• Controlling power amplifiers
• And many more…
