The M2-1VT5B.0004.570BD is a tricolour 5-digit meter for measuring of AC current /AC voltage signals TRMS and visual limit value monitoring via the display. The configuration happens via four front keys or via an optional PC-software. For further evaluations options like one analog output, one digital input and two switching points are available. Selectable software functions, direct limit value adjust- ment in operating mode and the compact installation depth of 89mm create a solid device concept.
