13.3 Design of the Redundant System
Components of the Rack
In the non-redundant version, the system is consists of only one channel (channel A). By retrofit-
ting modules for channel B, the system can be designed to be redundant in one rack for up to
64 measuring points.
NOTE: Retrofitting necessary modules for redundant design must only be carried out voltage-free,
i.e. the whole SUPREMA system must be switched off. The following new startup must be carried
out with consideration of the necessary configuration and parameter setting steps.
NOTE: When retrofitting, the Regulations for Handling Electrostatic Sensitive Components must
be followed!
Fig. 174 Modules of Rack
By adding further racks (8 max. per system) and the appropriate modules, the system can be ex-
tended up to 256 measuring points with up to 512 outputs.
