Product Overview:

 Function Introduction:

The WJ181 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange
 between 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 network interface
 communication.
 The communication method adopts MODBUS TCP protocol. TCP is a transport layer based
 protocol that is widely used and a reliable connection oriented protocol. Users can directly set module IP addresses,
 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, where user set  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, with strong
 anti-interference ability and high reliability. The working temperature range is-45 ℃ to+80 ℃.

 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 the product
 leaves the factory. During use, users can also easily program and calibrate themselves. Please refer to the product
 selection 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, the Link
 light (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 can
 also 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 pulses and
 protect the module.
