The perfect controller for small gas detection systems provides a Stand-Alone Safety System for any 2-sensor application.

The GG-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 GG-2.

The GG-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 works in tandem with the common horn relay. Analog outputs are standard, which can be sent to a 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 encountered in the food industry. The alarm log holds 10,000 events, so yesterday’s events will not go unnoticed.

The GG-2 controller utilizes a user-friendly LCD operator interface for all readout information and alarm function control. The controller is configured and ready to go out of the box with default setpoints loaded in the software. Simply enter the zone location names and adjust the alarm setpoints if necessary.

The backlit LCD displays real-time status of gas sensor concentrations and allows for custom programming via the user-friendly menu system. The GG-2 is compatible with all gas sensors with its 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.

The GG-2 is delivered ready to install. Use either the default setpoints or choose your own.
