The WJ181 remote I/O module can be used to measure one analog signal. 1. Analog signal input
12 bit acquisition accuracy, one analog signal input. All signal input ranges have been calibrated before theproductleaves the factory. During use, users can also easily program and calibrate themselves. Please refer totheproductselection for specific current or voltage input range. 2. Communication Protocol
Communication interface: RJ-45 network interface. The two indicator lights at the network port position, theLinklight (green light) stays on and the Data light (yellow light) stays on after the network cable is plugged in. Communication protocol: MODBUS TCP protocol is adopted to achieve industrial Ethernet data exchange. It canalso communicate with modules through TCP sockets. Network cache: 2K bytes (for both sending and receiving)
Communication response time: less than 10mS. 3. Anti interference
There is a transient suppression diode inside the module, which can effectively suppress various surge pulsesandprotect the module

Product Overview:
The WJ181 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchangebetween sensors and networks. The analog data from sensors can be forwarded to the network.

The WJ181 series products include power conditioning, analog acquisition, and RJ-45 networkinterfacecommunication. The communication method adopts MODBUS TCP protocol. TCP is a transport layer basedprotocol that is widely used and a reliable connection oriented protocol. Users can directly set module IPaddresses,subnet masks, etc. on the webpage. Can be used for monitoring and controlling the operation of sensor devices. The WJ181 series products are intelligent monitoring and control systems based on microcontrollers, whereuserset module IP addresses, subnet masks, and other configuration information are stored in non-volatile memory EEPROM. The WJ181 series products are designed and manufactured according to industrial standards, withstronganti-interference ability and high reliability. The working temperature range is -45 ℃to+80 ℃.
