System outputs assignable and
scalable to flow related parameters.
4-20mA outputs also provide a fault
indication by dropping to 2mA if
assigned to flow rate and under fault
conditions.
+30 V max. Same as TB2-3
Note
Auxiliary 4-20mA loops are assigned and spanned under menu control of Vo and PGEN
outputs.
