The MB3-3VT3VR.0H01.S70BD is a 30 points bargraph with a 3-digit digital display. Designed for high direct voltage / direct current signals (up to 300V and 1ADC). Configuration happens via 4 front keys or via optional PC-software. Optional available are one analog output and two switching points. Selectable software functions, as well as a direct limit value adjust- ment in operating mode and different kind of display options, as e.g. bars-/dot-operation for the bargraph, fullfill the standards of a modern device.
