Product Overview:
The WJ90 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Can be transmitted
The data from the sensor is forwarded to the network, or the data from the network is forwarded to the sensor.
The WJ90 series products include power conditioning, switch quantity acquisition, switch quantity output, and RJ-45 network interface communication. The communication method adopts MODBUS TCP
Protocol and Socket Protocol. TCP is a transport layer based protocol that is widely used and a reliable connection oriented protocol. Users can directly set up on the webpage
Set module IP address, subnet mask, communication protocol, etc. Can be used for monitoring and controlling the operation of sensor devices.
The WJ90 series products are intelligent monitoring and control systems based on microcontrollers, which store configuration information such as module IP addresses and subnet masks set by users
In non-volatile memory EEPROM.
The WJ90 series products are designed and manufactured according to industrial standards, with no isolation between signal inputs/outputs, strong anti-interference ability, and high reliability. operation temperature
Range -45 ℃ to+85 ℃.
Function Introduction:
The WJ90 remote I/O module can be used to measure eight switch signals and has eight switch outputs.
1. Switching signal input and output
8-channel switch signal input, capable of connecting dry and wet contacts. Please refer to the wiring diagram for details; 8-channel switch signal output with open collector output,
It can also be pulled up internally for output.
2. Communication Protocol
Communication interface: RJ-45 network interface. The two indicator lights at the network port position, Link light (green light) stays on after the network cable is plugged in, and Data light (yellow light)
It will flash irregularly.
Communication protocol: MODBUS TCP protocol and Socket free protocol are used to achieve industrial Ethernet data exchange. You can also access it directly through the webpage
