HDA.ISO Signal 1/2/3/4

The current 4 - -20 mA or voltage 2 - 10 V of the output signal is dependent on the

ISO contamination class 0.0 - 24.4 (resolution 1 class) as shown in the table below:

Current I ISO code Voltage U

I <4.00 mA Cable break U <2.00 V

I = 4.00 mA ISO 0 U = 2.00 V

I = 4.39 mA ISO 1 U = 2.20 V

I = 5.20 mA ISO 2 U = 2.60 V

I = 5.92 mA ISO 3 U = 2.96 V

I = 6.61 mA ISO 4 U = 3.30 V

I = 7.28 mA ISO 5 U = 3.64 V

I = 7.95 mA ISO 6 U = 3.97 V

I = 8.63 mA ISO 7 U = 4.18 V

I = 9.25 mA ISO 8 U = 4.62 V

I = 9.91 mA ISO 9 U = 4.95 V

I = 10.57 mA ISO 10 U = 5.28 V

I = 11.23 mA ISO 11 U = 5.61 V

I = 11.89 mA ISO 12 U = 5.94 V

I = 12.55 mA ISO 13 U = 6.27 V

I = 13.20 mA ISO 14 U = 6.60 V

I = 13.86 mA ISO 15 U = 6.93 V

I = 14.52 mA ISO 16 U = 7.26 V

I = 15.20 mA ISO 17 U = 7.60 V

I = 15.82 mA ISO 18 U = 7.91V

I = 16.48 mA ISO 19 U = 8.24 V

I = 17.13 mA ISO 20 U = 8.56 V

I = 17.79 mA ISO 21 U = 8.90 V

I = 18.45 mA ISO 22 U = 8.23 V

I = 19.11 mA ISO 23 U = 9.56 V

I = 19.82 mA ISO 24 U = 9.90 V

I = 20.00 mA ISO 24.28 U = 10.0 V

The current (I) or voltage (U) can be calculated for a given ISO contamination

class as follows:

I = 4 mA + ISO code x (20 mA - 4 mA) / 24.28

U = 2 V + ISO Code x (10 V - 2 V) / 24.28

The ISO contamination class can be calculated for a given current I or voltage U

as follows:

ISO code = (I - 4 mA) x (24.28 / 16 mA)

ISO code = (U - 2 V) x (24.28 / 8 V)
