Wiring with 2 input sensors
If 2 input sensors or input variables are used, observe
combination options in Table 3!
If 2 input sensors or input variables are used,
these must be free of potential or galvanical-
ly isolated against each other, on principle!
Otherwise, the transmitter may be damaged.
Exceptions:
• In case of a permitted input combination
mon (and approved) connections on Terminal 4.
E.g. direct voltage mV (Terminal 3, 4) & direct voltage V
(Terminal 6, 4)
• In case of a permitted input combination
same reference potential (e.g. earth) on Terminal 4
and 8
E.g. 2 thermocouples (on Terminals 3, 4 or 7, 8) with
earthed sensor tips or two mV inputs with a common
earth potential on Terminals 4 and 8.
In these cases, the specifi ed types of measurement
must be confi gured for earthed sensors.
