Consisting of one video and two balanced audio switches arranged as a changeover set with two inputs and two outputs, AMS-4172 relay changeover switches from IRT Electronics can be used in a wide variety of applications.
No terminations are provided on the board of these changeover switches, allowing the switcher to be used with signals of various types and impedances.
The video path utilises enhanced performance relays to deliver switching capabilities for high speed data signals up to 2.97Gb/s, and can be used with analogue video, 3G/HD/SD/ASI or G.703 data signals.
The audio path on these changeover switches can be used for balanced or unbalanced audio or control signals, such as RS232, RS422 and RS485, among others.
AMS-4172 switches are best suited for applications where a simple choice between two inputs or outputs is required and may be easily driven by detector circuits for automatic path selection.
The magnetic latching characteristic of the high performance relays allows momentary control and also provides for no change of path during power loss.
Local switching is possible using front panel push button switches, and remote switching can be achieved using external normally open or normally closed alarms.
To avoid accidental switching if bumped, the front panel switches on these changeover switches use a small delay. After a period of a few minutes, they will automatically revert back to remote mode.
For integration into central alarm and monitoring systems, the remote indication of tally status is provided, with SNMP (Simple Network Management Protocol) available for monitoring and control when using in an IRT frame fitted with SNMP capability.
Designed to fit IRT Electronic’s 1RU and 4000 series 3RU Eurocard frames, AMS-4172 relay changeover switches can be used alongside any other of the company’s analogue or digital Eurocards.
