Digital communication

I
PROFIBUS PA (PA+ / PA-)
U = 9 ... 32 v, I = 10 mA (normal operation), I = 13 mA (in the event of
an error / FDE)
Bus connection with integrated protection against polarity reversal.
The bus address can be set via the DIP switches in the device (with
dual-compartment transmitter housing only), the transmitter display or
the fieldbus.
The resistance R and condenser C form the bus termination. They must be installed when the device is connected to the end of the entire bus
cable. R = 100 Ω; C = 1 µF
