1 AUX I01+ Isolated Loop
Io1 External
+30V max. supply voltage allowed Not Used
2 AUX I01- Io1 4-20mA Out-
Io1 Signal Same output assignment as TB2-9
3 AUX I02+ Isolated Loop
Io2 External
+30V max. supply voltage allowed
4 AUX I02- Io2 4-20mA Out-
Io2 Signal Same output assignment as TB2-11
5 AUX I03+ Isolated Loop
Io3 External
System outputs assignable and scal-
able to flow related parameters.
4-20mA outputs also provide a fault
indication by dropping to 2mA if as-
signed to flow rate and under fault
conditions.
+30V max. Same as TB2-1
6 AUX I03- Io3 4-20mA Out-
Io3 Signal
7 AUX I04+ Isolated Loop
Io4 External
+30V max. Same as TB2-3
8 AUX I04- Io4 4-20mA Out-
put
Io4 Signal
-20mA loops are assigned and spanned under menu control of Vo and PGEN
puts.
