Reading the analog output
HDA.ISO Signal 1/2/3/4
The current 4-20 mA or voltage 2-10 V of the output signal, dependent on the
ISO contamination class being 0.0 - 24.28 (resolution 1 class), is described
as 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 = 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 current (I) or voltage (U) can be calculated for a given ISO
contamination class as follows:
ISO Code = (I - 4 mA) x (24.28 / 16 mA)
ISO Code = (U - 2 V) x (24.28 / 8 V)
