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
• GMA22-MS (24 V DC): 4x normally open contact

Each version is optionally available with a digital or analog input signal.

2811-709-006 EC 28 Gas Transmitter with Chlorine (Cl2), 0 - 50.0 ppm, No Display / Modbus by GfG

Advanced Technology

Wherever hazards are expected, the EC 28 transmitter and GfG's proven monitoring systems are the right choice for reliable surveillance. The ATEX-certified design, an integrated, Ex-proof buzzer, and bright alarm LEDs provide the highest safety in hazardous areas by including visual and audible alarms. The gas alarm not only alerts the person in the control room of hazards, but also the person on-site.

Easy handling

Smart sensor technology allows a user to install the transmitter or to replace a sensor within a few seconds just plug the sensor into the transmitter. Adjustments are done directly at the transmitter using touch keys or with the remote control (one-person calibration).

Remote Control RC2

Ammonia and hydrogen are lighter than air. With the transmitter installed close to the ceiling, GfG can provide permanently connected cables with plugs for the remote control, which allow the user to do all adjustments without having to climb a ladder. In addition, one remote control can be used for several transmitters, which helps cut costs and increase efficiency.

The remote control display is always identical to that of the transmitter, making inspection, service, and calibration considerably simple.

The remote control reads the current gas concentration and can be used as an external display.

Integrated Alarm Saves Money on Ex-proof Alarm and Wiring!

The EC 28 D model shows the current gas concentration on-site at the display of the transmitter and also at GfG s GMA controller.

The EC 28 DAprovides additional bright alarm LEDs and a buzzer avoiding costs for a separate Ex-proof horn and an Ex-proof light. You also save money on wiring to connect the controller and alarm devices.

In combination with GfG's flexible control units, the EC 28 provides various possibilities for reliable and cost-effective gas monitoring.

Reliable Measurement, Increased Safety, Minimized Cost of Operation

Accurate sensors and integrated temperature compensation provide the highest measurement accuracy. Low maintenance requirements and the long sensor life reduce your cost of ownership.
