The power provided for the measuring transducers is DC 24 V / 30 mA.

Feeding a signal to analog input 2, the controller´s setpoint can be influenced. The

influence can be scaled.

The following signals can be used:

- Input signals DC 0...1 V, DC 0...10 V, 0...20 mA, 4...20 mA

- 1 kΩ potentiometer in a 2-wire circuit

nalog input 1 (actual

value sensor)

setpoint shift or external

setpoint)
