2200-142 GMA22-MW/2 Versatile Controller, Configured for 2 measuring points, 4-20mA, power supply not included by GfG

Gases are also used (or may be found) in smaller facilities such as combined heat and power plants or cold stores. A reliable gas detection system therefore makes a significant contribution to the safety of people, your equipment and the environment. We developed the GMA22-M specifically for gas measurement in these applications. Up to four transmitters and relay modules can be connected to the controller. A display indicating the measured values, integrated visual and audible alarms, and four internal relays for additional safety measures complete the GMA22-M's extensive features.

Gases need to be monitored in many processes - regardless of the size of the plant. Even in smaller applications, a gas warning system is indispensable. The GMA22-M is the ideal controller for this purpose, if

• your application uses up to four transmitters
• you need to monitor toxic and combustible gases or oxygen
• a central display of measured values is required outside hazardous areas
• internal or external relays are required for safety measures
• you want acoustic and visual alarms to be initiated if gas dangers are present

Wide range of connection options

Using its RS-485 interface, the GMA22-M can be connected to up to four transmitters. In addition to the measured values, the controller also receives digital information such as status messages and service notifications. Alternatively, transmitters can also be connected through an analog 4-20 mA or 0.2-1 mA input.

If you are using any of GfG's ACDC capable transmitters, the analog lines can also transfer digital information on the analog lines (only via 4-20 mA). Many GfG transmitters can be calibrated remotely either using ACDC or digital integration. This simplifies service work significantly, allowing it to be performed by a single technician.

Exterior features

The GMA's dimensions (97 x 140 x 50 mm) are exceptionally small, allowing it to be mounted to a wall almost anywhere. The housing is protected against the ingress of dust and splash water according to IP64, making it suitable for use in demanding external conditions.

The 2.2-inch display comes with multicolor backlight. It lights up green in normal operation and red in the event of an alarm. Alarm levels are indicated by two red LEDs. The integrated horn also gives it an additional acoustic alarm. Two further LEDs indicate the operating status and special states in green and yellow. The pushbutton interface below the display allows for intuitive operation and alarm acknowledgement.

Internal and external relays

The GMA22-M has four integrated relays for initiating safety measures. Up to four additional GMA200-RT relay modules can be connected via the RS-485 interface. With 16 floating signal change-over contacts each, the number of relays is then increased to up to 64. The GMA200Config software is used to configure the GMA22-M and the relay modules. Alarms, faults and measured values can be recorded on a microSD card using a featured data logger, if required.

The GMA22-M is available in four different versions:

• GMA22-MW (230 V AC): 3x change-over contact, 1x normally open contact, power supply integrated
• GMA22-MW (24 V DC): 4x change-over contact

2203000 GMA200-MGSS/V0, Standard base unit, for 1 suction point, without changeover valve for test gas supply, with electronically controlled pump with flow control for 1-3 sensor units, 1x CC-sensor, 2x EC or IR-sensors by GfG

GfG Instrumentation is a global leader in the design and manufacture of gas detection products used to protect people, facilities and the environment. For over 50 years we have provided gas detection solutions for life critical health and safety applications. Our innovative and reliable gas warning and measurement systems provide the industry benchmark for accuracy, dependability, and cost-effective ownership.

Complex industrial processes and plants are still challenges for safety measures. Sealed spaces, pipelines and further hardly accessible areas as well as extreme ambient conditions are special demands on gas detection for process monitoring and the safety of plants and persons.

With the GMA 200-MGSS gas sampling system, GfG masters these challenges by combining the reliable GMA 200 controller with internal sensors and a electronic gas sampling feed pump. Samples of combustible and toxic gases can be taken from critical areas, processed and analyzed. Afterwards the gas sample can be fed back in the process or in safe areas.

Field-tested analysis

The gas sampling system is based on the GMA 200 controller and provides all of its' advantages:

Integrated relays

GMA 200-MGSS system includes comprehensive and fully programmable relays. Each controller is equipped with eight internal relays. Six of these relays can be freely programmed for alarms and further safety measures. This offers countless possibilities.

Clear display elements

The LEDs display the state of the gas sampling system, the operation mode, errors or service needed. In addition, the GMA 200-MGSS has a LCD graphical display, which continuously shows the current measurement data. In the case of an alarm, the red backlight of the display, the alarm LEDs as well as the relay LEDs will be activated and the active alarm will be shown in the display.

Operation via keyboard

Operation of the GMA 200-MGSS is through easy-to-use menus, and a simple 5 button interface for alarm acknowledgement, and viewing information on the status of the gas warning system, detectors and relays. The intuitive push-button controls make it easy to navigate through additional screens of information. The integrated display enables the reading of alarm levels through the controller LCD for easy hazard assessment.

Modular structure

The GMA 200-MGSS offers a wide range of flexibility and adjusts to your requirements. Due to the modular structure additional components can be added to the base version to perform measurement tasks.

Flame arrestor

If the gas sample is taken from potentially explosive atmospheres, they have to be protected from flames, which can be caused by sparks of electrical origin. For this purpose a flame arrestor can be integrated into the GMA 200-MGSS as an option. In the case that the gas will be led back to the potentially explosive atmospheres a further flame arrestor can be installed on the output of the GMA 200-MGSS.

Condensate trap

Gas samples may include pollution like dust particles as well as condensate. These impurities could damage the integrated sensors. The condensate trap filters the gas samples and greatly increases the lifetime of the sensors.

Water barrier

The water barrier prevents the unintentional intake of water or other liquids while taking gas samples.

Cooling coil

When analyzing gases from areas with extreme temperature, the sample must be cooled to prevent sensor damage.

Valve switching

The additional gas inlet for calibration gas or purge gas makes cleaning the gas channel and calibration of the device easy.

Features

• Efficient alternative to high-priced sampling systems
• Electronic sampling pump
• Fully automated flow control
• Internal gas distributor for one catalytic combustion sensor and two electrochemical sensors
• Condensate trap, water filter and flame arrestor

2220011 EC 22 Fixed Transmitter (no sensor), with display, 4-20 mA by GfG

The EC 22 Series are innovative and cost-effective transmitters for the detection of toxic gases or oxygen levels, but without the need for explosion protection.

Time-proven and innovative

The EC 22 is equipped with high quality GfG sensors. The transmitters are fitted with high-performance electronics for voltage stabilization, processing of readings, and temperature compensation. Follow up costs are minimized thanks to the long lifespan of the sensors.

Universal signal transmission

Either an analog or digital output signal can be transmitted by the EC 22 by means of a Modbus interface. Due to the different types of signal transmission, a transmitter from the 22 series can be connected to almost any gas detecting system, also as a supplementary or replacement transmitter on existing systems.

Signal processing

The embedded software of the EC 22 linearizes the measuring signal and compensates for the effects of temperature. As a result, correct readings are transmitted even with weather related fluctuations in temperature. In addition, the transmitter also offers the option of transmitting service, maintenance, and error messages to a connected gas measuring computer.

Weather protection

A weatherproof housing not only protects transmitters against exposure to wind and weather, but also against contamination and excessive temperatures caused by direct sunlight.

Optional colored graphic display and horn

The clear graphic display of the EC 22 is self explanatory and allows you to read the current status and other important information with ease. The display enables you to navigate effortlessly through the unit s concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm the display changes color from green to red. Two LEDs indicate the status.

Operation buttons

The buttons on the transmitter allow the unit to be calibrated and settings to be adjusted through the menu as needed.

Calibration adapter

In order to perform regular bump tests, a calibration adapter is used on the transmitter, which ensures a uniform and secure supply of gas.

Easy and convenient service

GfG offers full after-the-sale commissioning and field service support.

Features

• Long service life of the sensors
• High efficiency and low follow-up costs
• Sturdy plastic housing (IP-54)
• Cost effective single-man adjustment
• Affordable solution for many measuring tasks
