Product Overview:
The WJ165 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Can transmit
Forwarding sensor data to the network, or forwarding data from the network to sensors.
The WJ165 series products include power conditioning, switch signal acquisition, transistor output, and WiFi interface communication. The communication method adopts MODBUS TCP
agreement. TCP is a transport layer based protocol that is widely used, connection oriented, and reliable. Users can directly set the module IP address on the webpage
Subnet masks, etc. Can be used for monitoring and controlling the operation of sensor equipment.
The WJ165 series products are intelligent monitoring and control systems based on microcontrollers, where user configured module IP addresses, subnet masks, and other configuration information are stored
Exists in non-volatile memory EEPROM.
The WJ165 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 WJ165 remote I/O module can be used to measure three switch signals and has two switch outputs. It can be used as a 3-channel counter or 3-channel frequency measurement,
It can also output two PWM signals.
1. Switching signal input and output
3-way switch signal input, can be connected to wet contact signal, please add a pull-up resistor to dry contact; 2-way switch signal output with open collector output.
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.
