The QAS-200 Series Dual Channel Controller is a microprocessor based unit
that monitors input signals and provides relay outputs for alarm and control.
The units are switch selectable for either 4-20 mA DC input (standard) or
broad spectrum solid state sensor inputs for hazardous gas detection. Solid
state sensors can be either integrally or remote mounted to the 115 VAC
powered electronics encased in a Nema 4X surface mount enclosure.
Temperature compensation for solid state sensors is field selectable. Two
DPDT relays are provided, which can be configured to operate in common to
both channels or independently assigned. Relay time delays, both on and off,
and fail safe operation are field configurable. LED status indicator lights
provide alarm and sensor information for each channel. Optional digital LED
display(s) provide indication of 4-20 mA DC inputs (only) in engineering units.
