The Profibus slave has an internal power supply. This power supply
requires DC 24V. In addition to the electronics on the bus coupler, the
supply voltage is also used to power any modules connected to the
backplane bus. Please note that the maximum current that the integrated
power supply can deliver to the backplane bus is 3.5A.
The power supply is protected against reverse polarity.
Profibus and backplane bus are galvanically isolated from each other.
Attention!
Please ensure that the polarity is correct when connecting the power
supply!
Via a 9pin RS485 interface, you connect the Profibus slave with your
Profibus network.
The pin assignment of this interface is as follows:
