Product Description4-channel DI switch detection counter, MQTT protocol, online webpage display, WiFimodule WJ162Product Overview:The WJ162 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchangebetween sensors and networks. The switch data of the sensor can be forwarded to the network.The WJ162 series products include power conditioning, switch quantity acquisition, and WiFi networkinterfacecommunication. The communication method adopts MQTT protocol. TCP is a transport layer based protocol thatiswidely used and a reliable connection oriented protocol. Users can directly set module IP addresses, subnet masks, etc.on the webpage. Can be used for monitoring and controlling the operation of sensor devices. The WJ162 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 WJ162 series products are designed and manufactured according to industrial standards, withstronganti-interference ability and high reliability. The working temperature range is -45 ℃to+85 ℃Product model:WJ162 – WiFi - Form of antennaW external antennaN built-in antennaX suction cup antennaCommunication interfaceWiFi: Output as WiFi network interfaceCompany ProfileShenzhen Weijunrui Technology Co., LtdSince: 2011Specialty: The company's main products include analog acquisition modules, signal isolators/conversion modules, and signal transmittersCapacity: Produce 10000 per monthAdvanced Features:Switching to TCP/network/remote IO module, Modbus RTU to TCP, RS232/485 to Ethernet, analog signal (current/voltage/thermistor/frequency/displacement/speed/pulse) isolation transmitter, mV differential signal amplifier, isolation amplifier, micro power DC-DC module power supply, etcFunction Introduction:WJ162 General Parameters:The WJ162 remote I/O module can be used to measure four switch signals. Can be used as a 4-channel counter or4-channel frequency and speed measurement. 1, Switch signal input4-channel switch signal input, can be connected to dry contact NPN and wet contact PNP. Please refer tothewiringdiagram for details. 2, Communication ProtocolCommunication interface: WiFi network interface. It can connect to WiFi in the local area network andthenconnect to Ethernet. Communication protocol: Supports MQTT protocol and can connect to various MQTT servers such as AlibabaCloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, private cloud, etc. MODBUSTCPprotocol can also be used to achieve industrial Ethernet data exchange.
