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 will be associated with the equipment

will 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 or sales office and request the necessary information.

Product Description and Application

WBI122S01 adopts linear photoelectric isolation principle and average

value conversion technology to measure the AC and DC current in the

power grid or circuit in real time, and convert it to DC voltage (Uz)

output; it has many features such as universal AC/DC current input, high

precision, high isolation, wide frequency response, fast response time,

low drift, low power consumption, and wide temperature range. This

product adopts a card-mounted structure, terminal wiring, and easy

installation. It is suitable for isolated measurement of sine wave and DC

voltage.

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 need to warm-up the product for 3

minutes before use. The auxiliary power requires isolation

voltage≥2000V AC, DC current output ripple＜10mV.

3. Basic testing method for accuracy

(1) According to the terminal definition table to connect the

testing circuit;

(2) The testing must to be done by under the following

conditions；

Power supply: nominal value±0.5％, ripple≤5mV

Ambient temperature: 25℃±5℃

Relative humidity: RH(45～75)％

Accuracy for Signal Power Source instrument: 0.05

(3) Warming up the transducer for 3 minutes

(4) Use the input monitoring table V1 to monitor the output of

the signal source and give an arbitrary input value Ir within

the range of the sensor. Assuming that the input

specification of the sensor is 1A and the output

specification is 5V, the theoretical output value UZ of the

sensor is calculated by the following formula :

Uz = 5V×Ir/1A

(5) Use the output monitoring table V2 to measure the voltage

output value U0 at the output end of the sensor, and the

basic reference error γ of the sensor is calculated as

follows:

γ= (U0－Uz)/5V×100

(6) Repeating (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 store
