Quintech RFS 2150/2 Manual

General Description:
The RFS21502BAA000 L-Band RF Sensing Switch provides two (2x1) L-Band sensing switches which detects
the presence of RF (primary) and provides the ability to switch to backup (secondary) on loss of primary. Each
of the sensing switches utilizes a DPDT high frequency relay that has the off path terminated into 75 Ω. The
primary RF input is filtered, amplified, and detected to operate the relay. When the input level is above the
preset threshold, which is adjustable using the front panel up/down pushbuttons, the relay is energized and the
primary signal path is selected. When the signal falls below the preset threshold, the relay is de-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.
