FUNCTION CHARACTERISTICS
4 FUNCTION CHARACTERISTICS
4.1 HARDWARE
Device layout
Power supply board
All the components necessary for conversion and stabilization functions are present.
Two versions are envisaged suited to the input ranges 24...48 V and 115...230 V.
The circuit provides stabilized voltages of +10 V and -10 V, required for the analogue measurement,
+24 V for relays and +5 V for supplying the digital circuits.
CPU module
This circuit board contains all the circuits necessary for performing the analogue and digital pro-
cessing of the signals.
