- Page 2 WBI412M05 AC Current Sensor 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.
- Page 3 Product Description and Application WBI412M05 uses a special isolation module to measure the AC current in the grid and circuit in real time and transform it into the DC voltage (Uz) output of the standard vertebra; with high precision, high isolation, low drift, low power consumption and wide temperature range. It has strong anti-interference ability and wide working power range.
- Page 4 Terminals definition Working power ground(GND) Current input（IN-） Positive voltage output (OUT+) Current output（IN+） Negative voltage output (OUT-) Positive working power(+E) Non-identified terminals cannot be used！ Key Technical Data: 1. Input: 0.5A, 1A, 2A, 3A, 4A, 5A AC; 2. Output: 0-20mA, 4-20mA DC 3.
- Page 5 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.
- Page 6 output value Vz should be calculated as: Vz = 5V×Ir/50A (5) Using output monitoring meter V2 to measuring the output voltage V0 of the sensor, the basic introduced errorγof the sensor 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 sensor, it shows the sensor’s accurate grade is qualified.
