6.4 Analog Outputs
There are 3 analog outputs per channel. These outputs are configurable in terms of
function, content and behavior through the instrument menus. Analog outputs are used
to output a voltage or a current which is a function (e.g a linear characteristic) of a
measurement: AOut =
f (M). Analog outputs can be typically connected to a PLC.
Knowing the function ( f ), the PLC can compute the value of the measurement.
Two types of instrument hardware are available:
• measurement board with current output (I = 0-20 mA or 4-20 mA)
• measurement board with voltage output (U = 0-5 V)
