Product Overview: The WJ161 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 WJ161 series products include power conditioning, switch quantity acquisition, and WiFi networkinterfacecommunication. The communication method adopts MODBUS TCP protocol. TCP is a transport layer basedprotocol that is widely used and a reliable connection oriented protocol. Users can directly set module IPaddresses,subnet masks, etc. on the webpage. Can be used for monitoring and controlling the operation of sensor devices. The WJ161 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 WJ161 series products are designed and manufactured according to industrial standards, withstronganti-interference ability and high reliability. The working temperature range is -45 ℃to+85 ℃

Function Introduction: The WJ161 remote I/O module can be used to measure 1 encoder signal, or set as 2 independent counters or DI statusmeasurement. 1、 Signal input 1 encoder signal input or 2 independent counters, can be connected to dry and wet contacts, and the input typecan be set through commands. 2、 signal output 1-channel DO signal output, NPN with internal pull-up, output high level approximately equal to the power supplyvoltage, low level approximately 0V, can directly drive the intermediate relay with low level. 3、 Communication Protocol Communication interface: WiFi network interface. Can connect to WiFi within the local area network. Communication protocol: MODBUS TCP protocol is adopted to achieve industrial Ethernet data exchange. It canalso communicate with modules through TCP sockets. Network cache: 2K bytes (for both sending and receiving) Communication response time: less than 10mS. 4、 anti-interference There is a transient suppression diode inside the module, which can effectively suppress various surge pulsesandprotect the module
