Hydac CS1000 series - HDA.NAS Signal 1;2;3;4

Reading the analog output
HDA.NAS Signal 1/2/3/4
The current or voltage range is dependent on the contamination class
according to NAS=0.0 - 14.0 (resolution 0.1 class).
Current I
NAS class / error
Voltage U
I < 4.00 mA
Cable break
U< 2.00 V
I = 4.00 mA
NAS 0
U = 2.00 V
…
…
…
I = 20.00 mA
NAS 14.0
U = 10.00 V
The current (I) or voltage (U) can be calculated for a given NAS
contamination class as follows:
I = 4 mA + NAS class x (20 mA - 4 mA) / 14
U = 2 V + NAS class x (10 V - 2 V) / 14
The current (I) or voltage (U) can be calculated for a given NAS
contamination class as follows:
NAS class = (I - 4 mA) x (14/16 mA)
NAS class = (U - 2 V) x (14/8 V)
