Current I = ISO code / error Voltage U =
I = 15,62 mA ISO 19 U = 7,81 V
I = 16,19 mA ISO 20 U = 8,10 V
I = 16,76 mA ISO 21 U = 8,38 V
I = 17,33 mA ISO 22 U = 8,67 V
I = 17,90 mA ISO 23 U = 8,95 V
I = 18,47 mA ISO 24 U = 9,24 V
I = 19,20 mA ISO 24,28 U = 9,60 V
19,2 mA < I < 19,8 mA Not defined 9,60 V < U < 9,90 V
19,8 mA < I < 20 mA No measured value 9,90 V < U < 10 V
The current (I) or voltage (U) can be calculated for a given ISO contamination
class as follows:
I = 4.8 mA + ISO code x (19.2 mA - 4.8 mA) / 24.28
U = 2.4 V + ISO Code x (9.6 V - 2.4 V) / 24.28
The ISO contamination class can be calculated for a given current I or voltage U
as follows:
ISO code = (I - 4.8 mA) x (24.28 / 14.4 mA)
ISO code = (U - 2.4 V) x (24.28 / 7.2 V)
ISO 4 / ISO 6 / ISO 14
The ISO x setting enables the value of a class to be continuously output via the
analog output.
