 Product Overview:

 WJ285 General Parameters:

 WJ285 module appearance diagram
 The WJ285 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 WJ285 series products include power conditioning, Pt100/Pt1000 temperature 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 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 WJ285 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 WJ285 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 ℃.
 Function Introduction:
 The WJ285 remote I/O module can be used to measure 8 Pt100/Pt1000 temperature signals.
 1. Temperature signal input
 12 bit acquisition accuracy, 8 temperature signal inputs. Measure temperature range-200~600 degrees. The
 product has been fully calibrated before leaving the factory. During 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, 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.
