Product Overview:
The WJ321 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Can transmit
The analog data of the sensor is forwarded to the network.
The WJ321 series products include power conditioning, analog signal acquisition, and WiFi network interface communication. The communication method adopts MODBUS TCP protocol. TCP
It is a transport layer based protocol that is widely used, connection oriented, and reliable. Users can directly set the module IP address and subnet mask on the webpage
Wait. Can be used for monitoring and controlling the operation of sensor equipment.
The WJ321 series products are intelligent monitoring and control systems based on microcontrollers. User set module IP addresses, subnet masks, and other configuration information are stored
Exists in non-volatile memory EEPROM.
The WJ321 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. Working temperature range -45 ℃ to+80 ℃.
Function Introduction:
The WJ321 remote I/O module can be used to measure one analog signal.
1. Analog signal input
16 bit acquisition accuracy, with one analog signal input. All signal input ranges have been calibrated before the product leaves the factory. When in use, users can also be very
Convenient self programming calibration. Please refer to the product selection for the specific current or voltage input range.
2. Communication protocol
Communication interface: WiFi network interface. Can connect to WiFi in the local area network.
Communication protocol: Using MODBUS TCP protocol to achieve industrial Ethernet data exchange. It can also communicate with modules through TCP sockets.
Network cache: 2K Bytes (both receive and send)
Communication response time: less than 10mS. 3. Anti-interference
There is a transient suppression diode inside the module, which can effectively suppress various surge pulses and protect the module.
