Analog output modules
Analog outputs (AO1–AO4)
0 / 4–20 mA (configurable, factory-set to 4–20 mA), common
negative pole, galvanically isolated from ground, freely con-
nectable to ground, max. gain relative to protective ground
potential 50 V, max. working resistance 750 Ω. Resolution
16 bit. The output signal cannot be lower than 0 mA.
Terminal assignment
An analog output is allocated in the sequence of the sample
components for each sample component. The sequence of
the sample components is documented in the analyzer data
sheet and on the type plate.
