SRA-8901-R
SRA-8901-R
12 G Bypass Protection Switch with Output Distribution
The SRA-8901-R is bypass relay protection card that installs in the openGear frame.聽 It supports SDI signals from SD to 12G, DashBoard control and monitoring, reclocked distribution of the primary signal and adjustable switching parameters.
PROTECTION FOR CRITICAL SIGNALS
As facilities transition to UHD, the cost of downtime of critical feeds remains a concern. Especially in air-chains, the SRA-8901-R provides the essential ability to automatically transfer to a stable bypass source upon failure of the primary signal.
RELIABLE, ROBUST AND COST-EFFECTIVE
The SRA-8901-R adds cost-effective reliability to SDI signal paths up to 12G.聽 Even under the most adverse conditions, such as upstream equipment failure or power loss to the frame, the SRA-8901-R maintains continuity of the bypass signal.
HIGH-DENSITY AND FLEXIBLE OPENGEAR SOLUTION
The SRA-8901-R is a high-density solution that can protect up to 20 signals in a single openGear frame.聽 Configuration and monitoring are provided through a centralized DashBoard interface, including the ability to tailor switching characteristics to the needs of the signal chain.
