Fig. 9.1.-1 Order number of REC 523
The REC 523 units differ from each other as to the number and type of measuring
inputs.
All the REC 523 hardware versions include the same number of digital inputs and
outputs, whereas the number of matching transformers and sensor inputs as well as
the auxiliary voltage range vary between the different hardware versions.
Software configuration and software number
Each REC 523 allows different software configurations based on separate functions
that can be activated from comprehensive libraries (refer to Section 5.1. REC 523
functions) within the scope of the processing capacity as well as the
I/O connections and analogue channels available, and considering the total CPU
load of the selected functions.
