Safety claim
The information in the safety claim of the equipment documentation is intended to ensure that
equipment is properly installed in order to maintain it in a condition.
It is assumed that everyone who would be associated with the equipment should be familiar with
the contents of that safety section, or this safety guide.
When electrical equipment is in operation, dangerous voltages will be present in certain parts of
the equipment (e.g. the input terminal). Failure to obverse warning notices, incorrect use, or
improper use may endanger personnel and equipment and course personal injury or physical
damage.
Before working in the terminal strip area, the equipment must be isolated.
Proper and safe operation of the equipment depends on appropriate shipping and handling, proper
storage, installation and commissioning, and on careful operation, maintenance and servicing.
The operating manual for the equipment gives instructions for its installation, commissioning, and
operation. However, the manual cannot cover all conceivable circumstances or include detailed
information on all topics. In the event of questions or specific problem, do not take any action
without proper authorization. Contact the appropriate WB technical sales office and request the
necessary information.

Product Description and Application
WBV332S01 converts input DC pure or pulsating voltage into a load independent output signal
DC voltage 0-5V or 0~10V. It has adopted modulation-demodulation isolation principle and
average measurement method for real time measurement of DC voltage from electric net.
The product has certain advantages of total galvanic isolation between input/output, high accuracy,
low drifting by temperature, and wide temperature bearable range, etc.

Instruction of Installation and Use
1. The product has adopted structure compliance with EN50022; suitable for DIN rail
mounting NS35/7.5, NS35/15. Installation steps are as following (please reference to
dimensional drawing):
Step 1: Immobilize one side of product‘s mounting trough to the DIN mounting rail;
Step 2: Pull out the spring clasp;
Step 3: Place whole mounting trough to the DIN mounting rail properly;
Step 4: Release spring clasp to make sure the installation.
2. The product has calibrated before out of factory. After correctly wiring, it can be
powered and used immediately. But for further precise signal sampling, user needs to
warm-up the product for 3 minutes before use.
a) The auxiliary power requires isolation voltage≥2000VAC, DC current output ripple
＜10mV, and multiple converters can share with one set auxiliary power together.
b) When measuring dc voltage exceeds 500 volts, the circuit needs adding a resistor to
divide the input dc voltage. The resistor is provided by Mianyang weibo Electronic,
and only for each type of transducers special use only.

(3) Warming up the transducer for 3 minutes
(4) Using output monitoring meter V1 to measuring the output of signal power
source instrument, set any input value which is within the measuring range of
the transducer Vr.(e.g. if input range is 100V, the output is 0-5V ). the expected
output value Vz should be calculated as:
Vz=5V×Vr/100V
(5) Using output monitoring meter V2 to measuring the output voltage V0 of the
transducer, the basic introduced errorγof the transducer should be calculated
as:
γ= (Vo－Vz)/5V×100
(6) Repeating step (4) (5), if calculated absolute value is less than the given
accuracy value of the transducer, it shows the transducer’s accurate grade is
qualified.
Caution:
1. Pay attention to the auxiliary power information, especially the auxiliary power grade,
and polarity, other wise will damage the product.
2. Pay attention to the wire connection; wrong terminal connection will cause
malfunction of the product and even damage the product;
3. Don’t dismantle the product, and carry with care to avoiding bump and fall of the
product;
4. If the product has been using under the environment with strong magnetic field
interference, please pay attention to the shield of input wire, and the output signal wire
should be as short as possible. For product intensive installation, the space between

each product should not be smaller than 10mm.
5. Only use identified terminals.
6. There is no lightening strike prevention circuit design in this product. For out door and
hazardous environment using, please add protective alternatives.
7. This product uses fire prevent ABS crust, its temperature withstand is only limited as
+85℃, higher than this limitation will cause the product deformation. Please use and
