AD-VC 1 GVD

Description

The digital multi-function measuring transformers of series VarioCheck AD-VC 1 are freely programmable digital measuring transducers with two analogue outputs and up to 2 limiting value relays. Extensive standard equipment and additional options solve almost all imaginable tasks of a modern evaluation. All measuring ranges and outputs can be freely parameterized. This can be carried out via the optional operating modul AD-VarioControl or via the programming software AD-Studio. VarioCheck AD-VC 1 fulfils all tasks of a universal and secure measuring value recording through integral function modules such as limiting value messages, freely adjustable hysteresis, selectable relay functions, time-delayed switching, automatic or manual simulation modus, free linearizing curves and a wide range of supply voltage.
