Key Features
- Simultaneously monitor two sensor locations
- Six onboard relays standard
- Alarm Log records and stores every event
- Industry standard linear 4/20 mA input can accommodate any gas sensor
- Simple menu-driven programming through the LCD operator interface
- Power supply can also drive external horn/strobes
- Watertight enclosure designed for washdown areas and outdoors
- Configurable for GasGuard sensor line and any other 4/20 mA gas sensor
- Horn relay silenceable from front-panel Silence key
The GasGuardian-2 can interface
to, but operate independently of,
plant control systems for a reliable
stand-alone safety system.
Multiple digital and analog outputs
provided on the GasGuardian-2
means no extra output boards need
to be added later for unforeseen
interfacing in the future.
The GasGuardian-2 has a total of 6
relay outputs, including one warning
and one alarm relay per channel, one
common fault relay, and one common
horn relay. An onboard buzzer that
works in tandem with the common
horn relay. Analog outputs are
standard, which can be sent to your
plant PLC or other 4/20 mA control
panel.
The watertight fiberglass
enclosure will stand up to
corrosive washdown, temperature
swings and any other harsh
environment often encountered in
the food industry. Since the alarm
log holds 10,000 events,
yesterday’s events will not go
unnoticed.

Benefits
- Low cost solution for small systems
- Easy, simple configuration
- Alarm log records all events
The GasGuardian-2 controller
utilizes a user-friendly LCD operator
interface for all readout information
and alarm function control. Out of
the box, the controller is configured
and ready to go with default
setpoints loaded in the software. Just
enter the zone location names and
adjust the low the high alarm
setpoints if needed.
The backlit LCD displays real-time
status of gas sensor concentrations
and allows for custom programming
thru a user-friendly menu system.
The GasGuardian-2 is compatible
with all gas sensors with it’s industry
standard 4/20 mA inputs. The power
supply is also powerful enough to
power external 24Vdc horn/strobes.
All wiring is safely enclosed inside
and easily accessed from the hinged
lid. All human interfacing is
performed via the waterproof
membrane keys on the outside, for
non-intrusive operation.
