Commissioning
7.1 Connections
Note: A working HART communication requires a minimum load resistance (e.g. input
resistance of input card) of 250
Ω
in the output circuit. Is this not available the internal 221
Ω
resistance can be used. Then the connection has to be done on terminals 3+/2- or 4+/6-.
The maximum output load is reduced to 479
Ω
.
