This item is mostly popular for the fact that it is able to display direct current, voltage and frequency information. There are versions with two relay outputs available, while the display range is four digits, with or without indication, from -9999 to 9999. The panel digital indication series VD4 can also display different physical measures, as the units can read both digital and analog signals. The versions accept input signals by voltage channel, direct or alternate current.

Note that the visualizer series in the VD4 product item can be equipped with two relay outputs and two comparing alarms on the displayed variable. The type VD4 potentiometer input also allows the display of the position as absolute or relative. There are several available versions, such as Vcc with one voltage input channel, and Vcc2R with one voltage input channel and two relay outputs.
