Function Introduction:
The WJ325 remote I/O module can be used to measure one Pt100/Pt1000 temperature signal.
1. Temperature signal input
16 bit acquisition accuracy, 1 temperature signal input. 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: WiFi network interface. Can connect to WiFi within the local area network.
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
