Product Overview:
The WJ190 product realizes signal acquisition between sensors and hosts, used to decode grating encoder signals. The WJ190 series products can be applied in Ethernet bus industrial automation control systems, automated machine tools, industrial robots, three coordinate positioning systems, displacement measurement, stroke measurement, angle measurement, speed measurement, flow measurement, product counting, and more.
The product includes signal isolation, pulse signal capture, signal conversion, and Ethernet communication. The communication method adopts ASCII code communication protocol or MODBUS TCP communication protocol. TCP is a transport layer based protocol that is widely used and reliable for connection. Users can directly set module IP addresses, subnet masks, etc. on the webpage.
The WJ190 series products are intelligent monitoring and control systems based on microcontrollers, where user set module IP addresses, subnet masks, and other configuration information are stored in non-volatile memory EEPROM.
The WJ190 series products are designed and manufactured according to industrial standards, with signal input/communication isolation, strong anti-interference ability, and high reliability. The working temperature range is -40 ℃ to+85 ℃.
Function Introduction:
The WJ190 remote I/O module can be used to measure one encoder signal, or set as two independent counters or DI status measurement.
1. Signal input
One encoder signal input or two independent DI counters, can be connected to dry and wet contacts. Please refer to the wiring diagram for details.
2. Communication Protocol
Communication interface: RJ-45 network interface. The two indicator lights at the network port position, the Link light (green light) stays on after the network cable is plugged in, and the Data light (yellow light) will flash intermittently.
Communication protocol: Supports MQTT protocol and can connect to various MQTT servers such as Alibaba 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.
3. 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.
WJ190 General Parameters:
(Typical @+25 ℃, Vs is 24VDC)
Input type: Encoder AB signal input, 1 channel (A0/B0).
Low level: Input<1V
High level: Input 3.5~30V
Encoder frequency range 0-5MHz
Encoder counting range -2147483648 ~+2147483647, using 4x counting, automatically saved when powered off. After positive overflow, it automatically increases from the minimum negative value, and after negative overflow, it automatically decreases from the maximum positive value.
The range of the DI counter is 0~4294967295 . It automatically saves when powered off and increases from 0 after a positive overflow.
Input resistance: 30K Ω
Communication: MQTT communication protocol or MODBUS TCP communication protocol or TCP/UDP
