Chapter 4 – Configuration
8 DC CHANNELS
The signal of the transducer (±10 V or 0-20 mA) is converted in to the desired physical measurement using a
first order transfer function with the parameters of gain () and offset () defined by the user:
where is the converted value and is the value read by the DC channel in Volts or Amps.
The RMS value of the DC channels (transducers) is calculated every cycle.
To add a new DC channel select the DC CHANNELS section and fill in the following:
The IDENTIFIER text field allows user to enter a single code for the channel being defined (maximum 12
characters). No editing allowed;
The INPUT scroll box allows user to define the input to which each DC channel is connected. No editing
allowed;
The FREQUENCY REFERENCE scroll box allows user to select a reference voltage circuit;
The GAIN and the OFFSET text field allows user to define the transfer connected transducer function;
The UNIT text field allows user to define the connected transducer unit (maximum 6 characters, letters only).
Once the DC channel is created, it shows in the configuration interface menu. When selecting the DC
channel, a screen shows the characteristics of the DC channel selected, as shown in Figure 26. It is
possible to edit the frequency reference, gain, offset and unit.
