Analog Inputs

The timing point control can be adjusted with a linear current signal. This signal can be supplied, for example, by a potentiometer, a pressure sensor for charging pressure, or a detonation controller.

With the analog process signal (current loop signal) at the analog current input, the timing point can be offset in the advanced or retarded direction within a defined range.

Similarly or additionally, the timing can also be influenced by an analog voltage signal at the corresponding input.

The levels of the analog inputs can be set in the range from 0 mA to 20 mA and 0 V to 10 V. You can make this configuration with the MICT. Refer to the section Timing – Analog Inputs.

At the voltage output (Analog Power), a configurable auxiliary voltage is supplied that can be used for supplying power to external sensors.

 

Configuration examples

In this example the analog inputs are configured in the Timing – Analog Inputs window as follows:

  • Input current: 4-20 mA
  • Input voltage: 0-5 V

Characteristic 4-20 mA / 0-5 V – Ignition timing adjustment toward retarded.

Characteristic 4-20 mA / 0-5 V – Ignition timing adjustment toward advanced.
