• Upper and lower limits separately adjustable
• Measure on own power supply
• Selection of measuring range by DIP-switches
• Adjustable voltage on relative scale
• Adjustable delay function (0.1 to 30 s)
• Output: 8 A SPDT relay N.E.
• For mounting on DIN-rail in accordance with
DIN/EN 50 022 (DPB01) or plug-in module (PPB01)
• 22.5 mm Euronorm housing (DPB01)
or 36 mm plug-in module (PPB01)

DPB01, PPB01
Mode of Operation
Connected to the 3 phases
(and neutral) DPB01 and
PPB01 operate when all 3
phases are present at the
same time, the phase
sequence is correct (not
DPB01...N and PPB...N) and
the phase-phase (or phaseneutral) voltage levels are
within set limits.
If one or more phase-phase
or phase-neutral voltages
exceeds the upper set level
or drops below the lower set
level, the red LED starts
flashing 2 Hz and the output
relay releases after the set
time period. In any case if
phase-neutral measurement
is selected both phasephase and phase-neutral
voltages are monitored. If the
phase sequence is wrong or
one phase is lost, the output
relay releases immediately.
Only 200 ms delay occurs.
The failure is indicated by the
red LED flashing 5 Hz during
the alarm condition.
Example 1
(mains network monitoring)
The relay monitors over and
under voltage, phase loss
and correct phase sequence.
In case of DPB01...N or
PPB01...N, the relay monitors over and under voltage.
Example 2
(load monitoring)
The relay releases in case of
interruption of one or more
phases, when one or more
voltages drop below the lower set level or exceed the
upper set level.
