Product Overview:
The WJ186 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Analog data from sensors can be forwarded to the network.
The WJ186 series products include power conditioning, NTC10K/NTC20K resistance signal acquisition, and RJ-45 network interface communication. The communication method adopts MODBUS TCP protocol. TCP is a transport layer based protocol that is widely used, connection oriented, and reliable. Users can directly set module IP addresses, subnet masks, etc. on the webpage. Can be used for monitoring and controlling the operation of sensor equipment.
The WJ186 series products are intelligent monitoring and control systems based on microcontrollers. User set module IP addresses, subnet masks, and other configuration information are stored in the non-volatile memory EEPROM.
The WJ186 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. Working temperature range -45 ℃ to+80 ℃.
Function Introduction:
The WJ186 remote I/O module can be used to measure temperature signals such as 1 NTC10K/NTC20K.
1. Temperature signal input
12 bit acquisition accuracy, 1 NTC temperature signal input. All signal input ranges have been calibrated before the product leaves the factory. When in use, users can also easily program and calibrate themselves.
2. Communication protocol
Communication interface: RJ-45 network interface. The two indicator lights at the network port position, after the network cable is plugged in, the Link light (green light) will remain on and the Data light (yellow light) will remain on.
Communication protocol: Using MODBUS TCP protocol to achieve industrial Ethernet data exchange. It can also communicate with modules through TCP sockets.
Network cache: 2K Bytes (both receive and send)
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.
