Supply voltage
Supply voltage is only connected to the controller module. The
supply to the other modules is transmitted via the plug between
the modules. The supply must be 24 V +/-20%. One transformer
must be used for each controller. The transformer must be a class
II. The 24 V must not be shared by other controllers or units. The
analog inputs and outputs are not galvanically separated from the
supply.
The + and – 24V input must not be earthed.
Transformer size
The power consumption grows with the number of modules used:
Module Type Number á Effect
Controller 1 x 8 = 8 VA
Extension module 200-series _ x 5 = __ VA
Extension module 100-series _ x 2 = __ VA
Total ___ VA
12
Example continued:
Controller module 8 VA
+ 1 extension module in 100-series 2 VA
------
Transformer size (least) 10 VA
