HDA.SAE Signal 1/2/3/4

The current or voltage range is dependent on the contamination class according to

SAE=0.0 – 14.0 (resolution 0.1 class).

Current I SAE class / error Voltage U

I < 4.00 mA Cable break U< 2.00 V

I = 4.00 mA SAE 0 U = 2.00 V

I = 4.11 mA SAE 0.1 U = 2.06 V

I = 4.23 mA SAE 0.2 U = 2.11 V

... ... ...

I = 5.14 mA SAE 1 U = 2.57 V

I = 6.29 mA SAE 2 U = 3.14 V

I = 7.43 mA SAE 3 U = 3.71 V

I = 8.57 mA SAE 4 U = 4.29 V

I = 9.71 mA SAE 5 U = 4.86 V

I = 10.86 mA SAE 6 U = 5.43 V

I = 12.00 mA SAE 7 U = 6.00 V

I = 13.14 mA SAE 8 U = 6.57 V

I = 14.29 mA SAE 9 U = 7.14 V

I = 15.43 mA SAE 10 U = 7.71 V

I = 16.57 mA SAE 11 U = 8.29 V

I = 17.71 mA SAE 12 U = 8.86 V

I = 18.86 mA SAE 13 U = 9.43 V

... ... ...

I = 19.77 mA SAE 13.8 U = 9.89 V

I = 19.89 mA SAE 13.9 U = 9.94 V

I = 20.00 mA SAE 14.0 U = 10.00 V

If the contamination class is given acc. to SAE, the current I or voltage U can be

calculated:

I = 4 mA + SAE class x (20 mA - 4 mA) / 14

U = 2 V + SAE class x (10 V - 2 V) / 14

If the contamination class is given acc. to SAE, the current I or voltage U can be

calculated:

SAE class = (I - 4 mA) x (14/16 mA)

SAE class = (U - 2 V) x (14/8 V)
