iWSN wireless 1 Rogowski Coil current measurement channel and 1 expansion interface sensing module(RoHS)

The iWSN series sensing module is a self-powered module for AC current, digital input and temperature measurement. It can harvest the demand electricity from CT induced current so that there is no necessary to supply the power line for power supply. By means of sub-1G RF communication interface, iWSN series can approach to the real wireless deployment. The diversified IO interface, such as split-core CT, Rogowski coil, NTC thermistor and dry contact DI, provides users more choices for various applications. Considering the maintenance and installation, the iWSN sensing module uses the DIP switch and rotary switch for configuration. Through the flexibility of the expansion interface and good price performance, the iWSN sensing module can be widely used in the application of saving power, big data analysis, and predict maintenance.
