Current I ISO contamination class / error Voltage U
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)
