Fig. 90 System Configuration/Maximum Loads
Fig. 91 MGO Module/Maximum Loads
When setting the number of modules allowable per rack, the following factors of influence have to
be observed:
-
The power of the sensors to be connected including the losses resulting from the cable lengths
(MAI module/ MIB module).
-
The currents of the modules connected to the relay driver outputs (MGO module/ MIB module:
GND terminal).
-
The power requirement of the system modules (see Fig. 148 Power Requirements of the Sys-
tem Modules).
-
The power available from the supply voltage.
For further details, see the tables in Chapter 10.11 and Chapter 14 and the operation and main-
tenance manuals of the sensors to be connected.
NOTE: A cooling fan must be installed and operated to prevent overheating in the installation
framework if more than 64 measuring points are fitted with MPI modules.
