Product Description Ordering Key
DUB01 and PUB01 are precise 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.

both AC and DC over or

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
ops below (or exceeds) the

set level (see hysteresis setting), or when power supply
is interrupted.
Example 2
(connection between ter
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 more than the
set delay time.
mi-
Provided that the voltage
has dropped below (or has
exceeded) the set point (see
hysteresis setting) the relay
releases when the interconnection between ter
Z1, Y1 or 8, 9 is interr
or power supply is interrupted 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
