Matters needing attention

    In Figure 1, figure 2, figure 3 and connecting method 4 must be in use, can not be saved in the R between VCC and CP, such as VCC direct access to the CP end of the switch sensor will cause permanent damage to the device, figure 1, figure 2, figure 3, figure 4 in the R range of R=VCC/IR(IRLess than 1A), in order to save the power consumption, the user can according to their own design to get the value of R, VCC in +224V R, general 1K50K. The best absorption current of 0.25mA100mA, according to the user and.

The use of 4. methods:

When the input current exceeds the set point of protection when the output is low, when the input current is below the current set point protection when the output is +VCC, the R current limiting resistor, when +V=5V R is generally not less than 1K,Figure 1For the test circuit.

 

Application notes:This product is suitable forMonitorThe grid current on the line is overrun, the electric equipment state is advantages of the product in the set range, without any power supply, can be remotely transmitted by the working status of the electric equipment and flow pressure protection switch, can completely replace the current market on the source of the sensor and active isolation module can provide power supply for you to solve the troubles and wiring.
