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 utilising a sub-1G RF communication interface, the iWSN series provide flexible 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 maintenance and installation needs, the iWSN sensing module uses a 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 a variety of application such as power saving, energy performance analysis, and predictive maintenance/condition monitoring.
NOTE: Requires Wireless Concentrator/interface module with Modbus communication.
