Monitoring Relays

Product Description

?TRMS 3-phase over and under voltage,

phase sequence and phase loss monitoring relays ?Detect when all 3 phases are present and have the

correct phase sequence (except for N versions)

?Available versions (W4) supplied between phase and

neutral

?Detect if all the 3-phase-phase or phase-neutral volt-ages are within the set limits

?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)

?LED indication for relay, alarm and power supply ON

Input Specifications

3-phase or 3-phase+neutral line voltage monitoring relay for phase sequence, phase loss, over and under voltage (separately adjustable set

points) with built-in time delay function.

Supply ranges from 208 to 480 VAC covered by two multivoltage relays.

Mode of Operation

Connected to the 3 phases (and neutral) D

B01 and P P B01 operate when all 3phases are present at the same time, the phase sequence is correct (not N versions) and the phase-phase (or phase-neutral)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 phase-phase 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 N versions, 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.

Output Specifications

Note

When DPB01 or PPB01 is used with phase indicator lamps (see examples in the following diagrams), the lamp H1 or H2might be dimly lit when there is a phase loss in L1 or L2. This might happen if the lamps used are the typical low power indi-cator lamps, and there are no other loads present.

This fact can be avoided by using W4 models. Note that the neutral must be always connected to the device.H1
