figure 9.2: Analogue set temperature as a function of the applied current signal of the external requirement
At the input of the external requirement module a current signal between 4 and 20 mA should be given,
because a current signal is compared to a voltage signal insensitive to electromagnetic disturbances and
voltage losses at the cables. With an internal resistor (500 Ohm) the current signal is converted into a
voltage signal.
