Quintech Electronics RFS 2150 1RU IF Redundancy Dual RF Sensing Switch

The Quintech Electronics RFS21502FAA000 RF Sensing Switch provides two (2x1) sensing switches which detect the presence of RF (primary) and provides the ability to switch to backup (secondary) on loss of primary. Each of the sensing switches utilize DPDT relays that terminate the off path with 75 Ω. The primary RF input is filtered, amplified, and detected to operate the relays. When the input level is above the preset threshold, which is adjustable using the front panel up/down pushbuttons, the relays are de-energized and the primary signal path is selected. When the signal falls below the preset threshold, the relays are 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.
