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)
