GMA200-MW16 Fixed Gas Detection Controllers, by GfG Instrumentation

GMA200-MW16 Monitors 16 digital or analog transmitters

The GMA200-MW16 Reliable controller for complex gas detection systems in a wall-mounted housing. Wherever gases are used or may be present in industrial and commercial applications, they must be monitored. A gas detection system consists of one or more transmitters which use sensors to detect gases and a controller which has a wide range of tasks. The GMA200-MW16 controller is ideally suited for complex gas detection systems with up to 16 digital or analog transmitters. Safety measures can be connected directly to the GMA200-MW16 using internal relays. The display will indicate the current measured values as well as any alarms or special states of the transmitters.

Fixed transmitters monitor combustible or toxic gases and vapors present in the ambient air as well as the oxygen concentration. A controller displays the measured gas concentrations centrally and processes the incoming signals. The GMA200-MW16 is the right choice if:

• you are monitoring gases with up to 16 digital or analog transmitters.
• you want safety measures to be operated via the controller.
• the measured values need to be displayed centrally.
• an acoustic and visual alarm is required on site.
• you want the operating status and alarms to be indicated by status LEDs

Versatile possibilities for application

The GMA200-MW16 controller and the connected transmitters constitute a fixed gas detection system for measuring toxic and flammable gases as well as oxygen concentration. Up to 16 digital transmitters can communicate with the controller using the RS-485 interface. Analog transmitters (up to 16) can be connected on 0.2-1 mA or 4-20 mA lines. The GMA200-MW16 is suitable for any GfG transmitter and any available gas type. This offers a large number of possible combinations of gases, measuring ranges, measuring points and Ex zones to be monitored simultaneously. The robust housing (IP65) for wall mounting can be installed in almost any location. The supply voltage is 100-230 V AC or 24 V DC.

Internal relays and extensions

Six internal relays with one normally open contact each can be programmed individually to implement safety measures. Two additional relays are available for fault notifications and maintenance. If your area of application requires it, the number of programmable relays can be increased to up to 70 (6 internal and 64 external relays). They are connected via the GMA bus interface. GfG's GMA200-RT and GMA200-RTD relay modules allow safety measures to be implemented in a decentralized manner, reducing the amount of cabling required.

Clear indicators for assessing the hazard situation

The GMA200-MW16 has a color-backlit 2.2-inch display on which the current measured values of the connected transmitters are indicated at any time. In the event of an alarm, the background color changes from green to red. At the same time, LEDs indicate the alarm level and the relay switching states. A local alarm will trigger a highly visible alarm light and a loud, integrated buzzer (100 dB(A)). Two input slots are available for push-buttons to acknowledge alarms.

Operation, visualization and data storage

The controller is operated using five push-buttons and the alarm is intuitively acknowledged the same way. The device can be configured via the mini-USB interface using a PC and the GMAConfig software. With the optional GMA200-VS software, all measured values and states of the connected transmitters can also be displayed decentrally on a PC or any screen. Equipped with a microSD card, the controller permanently stores measured values, average values, alarm events and faults at individually configurable intervals for evaluation.
