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
Occasional flashing.
Communication Protocol: Supports MQTT protocol and can connect to various MQTT platforms such as Ali Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, Private Cloud, etc
The server. MODBUSTCP protocol can also be used to achieve industrial Ethernet data exchange. It also supports communication protocols such as TCP/UDP/WebSocket
Discussion.
Network cache: 2KByte (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 regulate the internal digital signals
Filtering can also effectively suppress power frequency interference from the power grid.
