The iWSN-110X-PCT-DC can realize true wireless deployment through Sub-1G's RF communication interface. The diversified IO interface, such as split-core CT and NTC thermistor (Requires expansion module) 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.
