Product Overview:

WJ286 General Parameters:

The WJ286 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Can be transmitted
The analog data of the sensor is forwarded to the network.The WJ286 series products include power conditioning, analog acquisition, and RJ-45 network interface communication. The communication method adopts MODBUSTCP protocol. TCP
It is a transport layer based protocol that is widely used and a reliable connection oriented protocol. Users can directly set module IP addresses and subnet masks on the webpage
Wait. Can be used for monitoring and controlling the operation of sensor devices.
The WJ286 series products are intelligent monitoring and control systems based on microcontrollers, which store configuration information such as module IP addresses and subnet masks set by users
Exists in non-volatile memory EEPROM.
The WJ286 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. The working temperature range is -40 ℃ to+85 ℃.
Function Introduction:
The WJ286 signal isolation acquisition module can be used to measure eight NTC thermistor signals.
1. Analog signal input
12 bit acquisition accuracy, 8 analog signal inputs. All signal input ranges have been calibrated before the product leaves the factory. Users do not need to calibrate.
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: Adopting MODBUSTCP protocol to achieve industrial Ethernet data exchange. It can also communicate with modules through TCP sockets.
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 parameters
Word filtering can also effectively suppress power frequency interference from the power grid

(Typical @+25 ℃, Vs is 24VDC)

You can set the AD conversion rate to 2.5SPS, 5SPS, 10SPS, and 20SPS by sending commands. Channel conversion rate=AD
Conversion rate/number of channels opened)
Note: Please recalibrate the module after modifying the conversion rate, otherwise the measured data may have deviations. You can also specify the transfer when placing an order
We recalibrate the conversion rate according to your requirements when the product leaves the factory.
