3624-201 D-ReX PoS Gas Detector with LIM and 5 relays, Carbon dioxide (CO2) MK251-10, 0 - 1% vol. by GfG

Not all gases can be monitored directly at the measuring point. This may be because the maintenance of a remote sensor would be too complicated or because the target gas has to be broken down into detectable components first. This can be done using a pyrolyzer.

In these cases, the D-ReX PoS with its integrated pump is an ideal solution. The point of sampling (PoS) can be up to 100 feet / 30 meters away from the D-ReX. This also applies to the length of the recirculation hose.

Available Accessory:

• DIN rail
• PTFE hose
• Various particle filters
• Push-Pull plug-in adapter
• Angle braces

Features:

• 5x internal relays (form C, configurable)
• Smart sensors for more than 60 gases
• Hot-swappable smart sensor cartridge
• Tool-free maintenance
• Power-over-Ethernet (PoE) communication
• Web server for browser access
• Password-protected menu
• Interface: Analog outlet: 4 20 mA output; Digital: RS-485 (Modbus/RTU); 10/100 Mbit Ethernet (Modbus/TCP)
• Bright status and alarm LEDs
• Data logger to review sensor and alarm history

2200-RT GMA 200-RT Relay Module without 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.
