IRT-6170-AMS: 3G/HD/SD-SDI, ASI, G.703, Video, Audio Relay Changeover Switch

IRT-6170-AMS Home Page, PDF Brochure

The IRT-6170-AMS is a relay changeover switcher for video and audio applications. The video path is suitable for analogue and digital (up to 3G-SDI) video applications as well as unbalanced AES and Telco G.703 signals up to STM-1 rates. The audio path is suitable for balanced analogue stereo, data or balanced AES.

FEATURES:

  • One video and two audio changeover switches in one package.
  • Video path suitable for 3G/HD/SD-SDI, Analogue video, ASI, G.703 signals @ 2, 8, 34, 45, 144, 155 Mb/s, and unbalanced AES.
  • Audio path suitable for 2 balanced, or 4 unbalanced, audio or data signals, and balanced AES.
  • Married or independent operation.
  • Momentary Set/Reset control.
  • No path change on power fail.
  • Local or remote control.
  • DashBoard software monitoring and control.

IRT-6170 Block Diagram

The IRT-6170-AMS consists of one “video” and two “balanced audio” switches arranged as a changeover set with two inputs and two outputs. No terminations are provided on the board allowing the switcher to be used in a wide variety of applications and with signals of various types and impedances.

The “video” path uses enhanced performance relays to provide switching capabilities for high-speed data signals up to 2.97 Gb/s and may be used with analogue video, 3G/HD/SD/ASI or G.703 data signals.

The “audio” path may be used for balanced or unbalanced audio or control signals (RS232, RS422, RS485 etc).

The magnetic latching characteristic of the high performance relays allows momentary control and also provides for no change of path during power loss.

The IRT-6170-AMS is ideally suited to applications where a simple choice between two inputs or outputs is required and may be easily driven by detector circuits for automatic path selection.

Local switching is possible using front edge push button switches. Remote switching is possible using external normally open or normally closed alarms.

Front edge switches use a small delay to avoid accidental switching if bumped. After a period of a few minutes, the IRT 6170 AMS automatically switches back into remote mode.

Remote indication of tally status is provided for integration into central alarm and monitoring systems.

The IRT-6170-AMS is designed to fit the openGear standard 2RU frames which allow a mixture of cards from various manufacturers to be mounted within the same frame.

The DashBoard control software is available as a free download.
