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 and speed measurement.
 1,Switch signal input
 4-channel 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 connect to WiFi in the local area network and then
 connect to Ethernet.
 Communication protocol: Supports MQTT protocol and can connect to various MQTT servers such asAlibaba
 Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, private cloud, etc. MODBUS TCP
 protocol can also be used to achieve industrial Ethernet data exchange.
 Network cache: 2K bytes (for both sending and receiving)
 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.
