Product Descriptions

E821-DTU (2I2-400SL) is a remote control product that supports analog tracking and control acquisition. It supports wireless Modbus RTU protocol in control acquisition mode. This product is highly user-friendly, and users can easily and quickly integrate it into their own system to achieve remote control based on 433MHz wireless. The analog output of the receiving end can follow the analog input of the sending end, configured as bidirectional follow-up, and the analog output of the sending end can follow the analog input of the receiving end.

Product Features
