Product Description

4-20mA or 0-10V to network Modbus TCP and MQTT, WiFi acquisitionmodule

Product Overview:
The WJ321 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchangebetween sensors and networks. The analog data from sensors can be forwarded to the network.The WJ321 series products include power conditioning, analog data acquisition, and WiFi networkinterfacecommunication. The communication method adopts MODBUS TCP protocol. TCP is a transport layer basedprotocol that is widely used and a reliable connection oriented protocol. Users can directly set module IPaddresses,subnet masks, etc. on the webpage. Can be used for monitoring and controlling the operation of sensor devices. The WJ321 series products are intelligent monitoring and control systems based on microcontrollers, whereusersetmodule IP addresses, subnet masks, and other configuration information are stored in non-volatile memory EEPROM. The WJ321 series products are designed and manufactured according to industrial standards, withstronganti-interference ability and high reliability. The working temperature range is -45 ℃to+80 ℃.
