Source (passiv input card)
Sink (active input card)
a
The two DIP-switches are located at the front of the device. Settings made to the device with DIP-switches must
occur in a voltage-free state.
3.8
HART® communication
HART communicators (HHT) can be connected as shown in the basic circuit diagram. Test sockets (di-
ameter 2.3 mm) are integrated in the screw connection terminal blocks for this purpose.
