Input Specifications
DUB 01 C B23 10V
DUB01 and PUB01 are pre-
cise TRMS AC/DC over or
under voltage (selectable by
DIP-switch) monitoring
relays.
Owing to the built-in latch
function, the ON-position of
the relay output can be
maintained. Inhibit function
can be used to avoid relay
operation when not desired
(maintenance, transitions).
The LED's indicate the state
of the alarm and the output
relay.

Mode of Operation
DUB01 and PUB01 monitor
both AC and DC over or
under voltage.
Example 1
(no connection between ter-
minals Z1, Y1 or 8, 9 - latch
function disabled)
The relay operates when the
measured value exceeds (or
drops below) the set level for
more than the set delay
time.
It releases when the voltage
drops below (or exceeds)
the set level (see hysteresis
setting), or when power sup-
ply is interrupted.
Example 2
(connection between termi-
nals Z1, Y1 or 8, 9 - latch
function enabled)
The relay operates and
latches in operating position
when the measured value
exceeds (or drops below)
the set level for morethan
the set delay time.
Provided that the voltage
has dropped below (or has
exceeded) the set point (see
hysteresis setting) the relay
releases when the intercon-
nection between terminals
Z1, Y1 or 8, 9 is interrupted,
or power supply is interrupt-
ed as well.
The red LED flashes until the
delay time has expired or
the measured value has
dropped below the set point
(see hysteresis setting).
Note
When the inhibit contact is
opened, if the input signal is
already in alarm position, the
delay time needs to elapse
before relay activation.
