Multi-channel gas detection control unit GMA400

LCD display

Applications in which combustible and toxic gases or the concentration of oxygen need to be monitored are getting more and more complex - and so do the requirements they have for gas detection systems. The performance and technical possibilities of the GMA400-MT contribute to the safety of people, facilities and the environment even in the most challenging conditions. A single GMA400-MT can monitor up to 128 transmitters or measuring channels as well as 32 virtual transmitters for calculated parameters or environmental influences. The controller features an integrated network interface for Modbus TCP integration as well as access via a web interface. Up to 128 relays can be added to its eight integrated ones. In addition to the large color display giving you an overview of the measured values directly on site, decentralized display modules and large displays can be added for further visualization The role of transmitters in fixed gas detection systems is to monitor the ambient air for dangerous gas concentrations. Depending on the application, this can include the lower explosion limits of combustible gases and vapors short-term and long-term values of toxic gases or the oxygen concentration. To choose the right transmitter and sensor technology, you will have to consider several different factors, such as the type of gases and measuring ranges, environmental conditions and potentially explosive areas. A controller's role is to then evaluate and display the measured gas concentration as well as activating safety measures. The GMA400-MT is the right choice for you if you need a controller for up to 128 measuring points
