 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.
