Voltage Monitors
Voltage Monitor E-1079-... monitors set MAX
and/or MIN voltage limits. The response can be
directly preset by the digital switches on the
front of the housing. When the set limits are
exceeded, the applicable relay (change over)
will switch off. The response delay may be set
between 0.2 and 30 s. Relay status, operating
voltage and adjustment error are indicated by
LEDs.

Technical data
Voltage Monitor E-1079-600 monitors DC or
AC voltages with set tolerances. Two LEDs
indicate the operating status and over limits,
with an opto coupler providing a physically iso-
lated output signal. The power requirement of
the Monitor is taken from the input signal.
