This product has reached end of life and is no longer available. Please contact us for a suitable replacement from Quintech.
The Quintech RFS 0070 RFS00702FAA000 RF Sensing Switch provides two (2x1) RF detector switches in a single RU enclosure. Each of the RF sensing switches utilizes an DPDT RF relay to switch either the primary or secondary signal input to the output. The pilot frequency is coupled from the primary signal input, filtered, amplified, and detected to operate the relay. When the input level is above a preset threshold, which is adjustable using the front panel potentiometer, the relay is deenergized and the primary signal path is selected. When the signal falls below the preset threshold, the relay is energized and the secondary signal path is selected. A front panel slide switch has been included to allow manual override to the secondary input. The rear panel has been equipped with relay contact alarm outputs and a remote override via contact closure.
Features & Benefits
IF redundancy switches provide automatic backup for signal continuity thereby maintaining your revenue stream.
Facilitates scheduled maintenance activity with no downtime.
Eliminates the need for emergency service, permitting maintenance on a managed schedule.
Rear panel mounted barrier strip provides the interface for a contact closure summary alarm and remote override.
The threshold is adjustable via front panel for adjustment sensitivity and flexibility.
Ideal for redundancy switching applications for failed LNB’s, up converters, down converters, antenna rain fade and unmanned facilities.
Ultra-reliable 1:1 redundancy for backup of fiber links.
The RFS 2150/2 with serial control provides the ability to remotely control the RF sensing switches via RS232.
