2212006 CI 21 Fixed Gas Transmitter with External Sensor, Ammonia (NH3), 0 to 10000 ppm by GfG

The charge carrier injection (CI 21) sensor is a progressive development to improve upon current ammonia refrigeration detection methods. With CI 21 technology sensor life is no longer limited to ammonia exposure levels. This reduces replacement costs associated with electrochemical sensors.

Charge carrier injection technology also eliminates false alarms frequently associated with metal oxide sensing (MOS). These, along with other features, provide reliable, cost effective, longterm safety.

The CI 21 transmitter is an advanced development to which all other ammonia transmitters will be compared.

• Stable long-life charge-carrierinjection sensor
• Sensor is unaffected by exposure to high gas concentrations
• Low temperature operation to -40oF
• Low cross-sensitivity
• Eliminates costly false alarms
• Low cost of ownership

2210-00410 25 Series Controller Panel with Four Input Channels, Horn and Strobe With 2 Amp Power Supply Requires Hard Wiring by GfG

Simple and Effective

The 25 series control panel is available in a single channel (2210-001 and 2210-00110) or a one to four channel (2210-004 and 2210-00410) version. The panel comes complete with controller, local display horn and strobe. The single channel version also features a 4-20 mA output

Alarm Points

Each alarm can be adjusted separately. The alarm values can be freely adjusted within the detection range. Every alarm point value can be factory programmed to be latching/non-latching and resettable/non-resettable.

Alarm Relays

The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns.

Transmitters/Sensors

The 25 series control panel may be connected to any available GfG transmitter for detection of oxygen (O2), combustible gases (LEL) or any transmitter from a wide range of toxic gases.

Features

• Complete controller package available in single channel or 1-4 channel configurations
• Compact design
• Intuitive push button operation
• 4-20 mA input standard (factory configurable to 0.2-1 mA)
• 3 user-adjustable alarm hysteresis
• Rugged metal housing
• Easy installation
• 4 relays (3 alarm and 1 fault)
• Factory configured alarm functions include: Latching/non-latching, Resettable/non-resettable, Time delay, Rapid rise alarm for combustible setups
• Local display, horn and strobe
• 4-20 mA output (2210-001 and 2210-00110 only)

2200-RTD GMA 200-RTD Relay Module with Display, 16 Relay (Change Over Contact) by GfG

For more than 50 years, the key goal of GfG has been to meet the highest demands of occupational health and safety, industrial equipment reliability and environmental protection. This goal has been reached by developing innovative and reliable gas warning systems. Development of the new GMA 200 controller satisfies these requirements while taking into account suitability testing in line with ATEX Directive 94/9/EC. If switching functions for explosion protection are required, the GMA 200 controller is the optimal solution. It also meets the requirements for gas warning systems in non-hazardous locations.

The GMA 200-RT / RTD Relay modules

Using a GMA 200-RT / RTD relay module, it is possible to extend the GMA 200 controller by 16 additional freely configurable relays. A total of 4 additional relay modules and thus 64 additional relays can be managed through the GMA 200 controller. Digital connection of the GMA RT / RTD relay module to the GMA 200 controller enables the local positioning of the relay modules. This local installation of the relay module results in significant cost savings through reduced cabling and installation costs.

GMA 200-RTD Graphical display

The clearly structured layout of the GMA 200-RTD relay module with graphical display enables the quick detection of hazardous situations. Currently measured values are displayed on the LCD graphical display. In the event of gas alarms, the display lighting is automatically activated with a red background.

Operation via keyboard on the GMA 200- RTD display

Five buttons enable operation at the GMA 200. The main functions of the keyboard are the acknowledgement of alarms and the menu-driven operation. Information on the status of the relays can be retrieved in the operating menu.
