Product Overview:
The WJ162 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Can transmit
The switch data of the sensor is forwarded to the network.
The WJ162 series products include power conditioning, switch signal acquisition, and WiFi network interface communication. The communication method adopts the MQTT protocol. TCP is based on
The transport layer protocol is a widely used, connection oriented, and reliable protocol. Users can directly set module IP addresses, subnet masks, etc. on the webpage. can
Used for monitoring and controlling the operation of sensor equipment.
The WJ162 series products are intelligent monitoring and control systems based on microcontrollers, where configuration information such as module IP addresses and subnet masks set by users are stored
Exists in non-volatile memory EEPROM.
The WJ162 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. Working temperature range -45 ℃ to+85 ℃.
Function Introduction:
The WJ162 remote I/O module can be used to measure four switch signals. Can be used as a 4-channel counter or 4-channel frequency speed measurement.
1. Switching signal input
4-way switch signal input, can be connected to dry contact NPN and wet contact PNP, please refer to the wiring diagram for details.
2. Communication protocol
Communication interface: WiFi network interface. It can be connected to WiFi in the local area network and then to Ethernet.
Communication protocol: Supports MQTT protocol and can connect to various MQTT platforms such as Alibaba Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, Private Cloud, etc
The server. MODBUS TCP protocol can also be used to achieve industrial Ethernet data exchange.
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.
