3.7 Output of current with HART communication
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.
3.9 Output Voltage
3.10 Voltage supply
The voltage supply is fed in via the connection terminals 1.1 (+) und 1.2 (-) (DC/AC 24 to 230 V).
