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.FAQQ: How to contact you?A: Please contact us via email or online customer service
