The series DGN 75AC offers a whole range of high accuracy program-
mable panel meters. Each instrument is equipped on its front face with a
five 14mm high red digits display, whose brightness suits applications in
industrial control rooms perfectly.
They allow display, control and transmission of data from alternating vol-
tage, alternating current and of frequencies from alternating signals.
