Low level: Input<1V High level: Input 3.5~30V Frequency range 0-5MHz (all channels input simultaneously) Encoder counting range-2147483647 ~+2147483647, using 4x counting, automatically saved when powered off DI counter range 0~4294967295 , automatically saved when powered off Input resistance: 30K Ω Communication 1: Protocol RS-485 or RS-232 standard character protocol and MODBUS RTU communication protocol The baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set on the webpage Address (0-255) can be set on the webpage Communication 2: MQTT communication protocol or MODBUS TCP communication protocol or TCP/UDP communication protocol Communication response time: 100 ms maximum Working power supply:+8~32VDC wide power supply range, with internal anti reverse and overvoltage protection circuits Power consumption: less than 1W Working temperature:-45~+80 ℃ Working humidity: 10~95% (no condensation) Storage temperature:-45~+80 ℃ Storage humidity: 10~95% (no condensation) Isolation withstand voltage: DI input and power supply are grounded together, and 1000V isolation is provided between them and the communication interface. Dimensions: 79 mm x 69.5mm x 40mm The WJ166 remote I/O module can be used to measure four encoder signals, and can also be set as an 8-channel independent counter or DI status measurement. 1,Signal input 4-channel encoder signal input or 8-channel independent counter, can be connected to dry and wet contacts. Please refer to the wiring diagram for details. 2,RS485/232 communication protocol Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface, please specify when ordering and selecting. Communication Protocol: Supports two protocols, the character protocol defined by the command set and the MODBUSRTUcommunication protocol. The module automatically recognizes communication protocols and can achieve network communication with various brands of PLCs, RTUs, or computer monitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. No verification. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; The communication network can reach a maximum distance of 1200 meters and is connected through twisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication response time less than 100mS. 3,WiFi 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. It also supports communication protocols such as TCP/UDP/WebSocket. Network cache: 2K bytes (for both sending and receiving) Communication response time: less than 10mS. 4,anti-interference Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively suppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power frequency interference from the power grid.FAQQ: How to contact you?A: Please contact us via email or online customer service
