UNIVERSAL INPUT
The Controller has two universal inputs (universal input 1, universal input 2) which can be assigned independently for tem-
perature inputs. In addition to RTD and thermocouples, resistor, DC and potentiometer inputs are also usable. The resistor,
DC and potentiometer input is scaled into a temperature range.
Universal input 1 is usually assigned as PV input signal for loop 1, while universal input 2 is for loop 2. Universal input 2
signal can be cascaded into the loop 1 SP.
