E-1079
The E-T-A Voltage Monitor E-1079 is designed to monitor DC voltages.
The MAX and/or MIN limit value can be directly set by means of the digital
switches provided on the front of the housing. Voltage falling below, or
rising above, the preset limit causes the integral relay (change-over
contact) to de-energise.
The switching delay to compensate for short duration voltage fluctuations
may be set between 0.2 and 30 s by means of the
potentiometer. The monitors operate on the closed-circuit principle, i.e.
voltage failure has the same effect as an incorrect voltage level. LEDs
provide indication of relay status, operating voltage and adjustment
errors (LEDs extinguish when there is a fault).

E-1079-600
The electronic E-T-A Voltage Monitor E-1079-60. is designed to monitor DC
or AC voltages against falling below, or rising above, preset tolerance
limits. Two LEDs indicate relay status or overlimits; an opto
coupler output provides a physically isolated signal.
The device is available either with a (non-conducting) N/O or a
(conducting) N/C contact. It is powered by the measuring signal so that
there is no need for an additional power supply.
