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. Thanks to its network interface, you will need no additional hardware to integrate it into superordinate safety systems or for gaining remote access to the device. Up to 192 external relays can be added to the eight integrated ones, and the central display of measured values on the large color screen can be expanded with display modules for local visualization.
