2200-134 GMA22-MW/3 Versatile Controller, Configured for 3 measuring points, 4-20mA, with internal power supply 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
• GMA22-MS (230 V AC): 4x normally open contact, power supply integrated

4000-010 GMA400-MT 16/80 GMA400 Controller, for 80 measuring points by GfG

Fixed gas detection systems, consisting of one or more central controllers and transmitters, are used in applications requiring continuous monitoring of toxic gases, combustible gases and vapors or oxygen. In situations which make standard solutions hit their limits because of the number of monitored measuring points or zones, the GMA400 controller provides new options for creating complex gas detection systems.

Up to 16 analog or 128 digital GfG transmitters can be connected to one GMA400 controller. An additional 32 virtual transmitters monitor calculated parameters, such as mean values, minimum / maximum values and environmental influences. The compact DINrail-mounted controller (T35) is installed in control cabinets or wallmounted housings.

Digital Communication on Analog Lines

ACDC is a patented technology which allows transmitters to communicate information that goes beyond the plain measured value to the central evaluation unit, using 3-wire 4-20mA line that were already in place. It also receives digital signals from the controller in return. This solution is a significant benefit to your system, as it allows you to use existing analog loops for high-speed transmission of digital data.

Using the analog cabling you already had will allow you to significantly reduce the costs of updating your system – while controllers and ACDC-capable transmitters will still be able to communicate like in a digital system.

The benefits of digital communication

• Bidirectional transmission of additional data, such as mean values or status notifications
• Maintenance of transmitters which are difficult to access using remote calibration
• Higher accuracy and immunity to interferences

Up to 16 ACDC-capable transmitters can be connected directly to the ACDC-capable GMA400. The GMA400-AT24 module lets you upgrade that number to 128. This makes the GMA400 a perfect choice for integrating modern gas detection systems into old but functional infrastructures, as well as for retrofitting or expanding them.
