Product Overview:
The WJ170 product achieves transparent data exchange between sensors and networks to control device operation. It can be generated through network control of relays
The switch quantity is used to control the operation of the equipment.
The WJ170 series products include power conditioning, relay control, and WiFi network interface communication. The communication method adopts MODBUS TCP protocol. TCP
It is a transport layer based protocol that is widely used, connection oriented, and reliable. Users can directly set the module IP address and subnet mask on the webpage
Wait. Can be used for monitoring and controlling the operation of sensor equipment.
The WJ170 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 WJ170 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 WJ170 remote I/O module can be used to control the output of two switch signals.
1. Switching signal output
Two C-type relay signal outputs with normally open and normally closed contacts.
2. Communication protocol
Communication interface: WiFi network interface. Can connect to WiFi in the local area network.
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 is a transient suppression diode inside the module, which can effectively suppress various surge pulses and protect the module.
