Pt100/Pt1000 temperature signal measurement
Product Overview:
The WJ185 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Can transmit
The analog data of the sensor is forwarded to the network.
The WJ185 series products include power conditioning, Pt100/Pt1000 temperature signal acquisition, and RJ-45 network interface communication. 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 the module IP on the webpage
Address, subnet mask, etc. Can be used for monitoring and controlling the operation of sensor equipment.
The WJ185 series products are intelligent monitoring and control systems based on microcontrollers. User set module IP addresses, subnet masks, and other configuration information are stored
Exists in non-volatile memory EEPROM.
The WJ185 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 WJ185 remote I/O module can be used to measure one Pt100/Pt1000 temperature signal.
1. Temperature signal input
12 bit acquisition accuracy, 1 temperature signal input. Measure temperature range -200~600 degrees. All products have been calibrated before leaving the factory. When in use, the user
It can also be easily self programmed and calibrated.
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 are transient suppression diodes inside the module, which can effectively suppress various surge pulses and protect the module
