2.2 Construction of the Unit
The modules of the SUPREMATouch are mounted in a rack. For expanded systems, additional
modules can be placed in a second rack or installed on top hat rails in a switch box. Data is ex-
changed between the modules over a CAN bus, which makes it possible to transmit data over dis-
tances of up to 1,000 m. For measurement tasks that require redundant signal input and
processing, additional modules can be added at any time to expand the gas warning system.
The installation site of the modules must be outside hazard areas 0, 1, and 2 and be free of ignit-
able, explosive, or corrosive gases.
The sensors must have the type of protection against ignition prescribed for the installation site.
The connection between the input module of the SUPREMATouch and the sensors is established
by a shielded remote-measurement cable of the 2, 3, 4 or 5 wire type.
For servicing, the sensors can be electrically isolated from the SUPREMATouch by mechanically
disconnecting the plug-in connection [MAT, MAT TS modules].
The following block circuit diagram shows the possible layout of a non-redundant system.
