(Typical @+25 ℃, Vs is 24VDC)
Input type: switch input, 8 channels (DI0~DI7). Low level: Input<1V
High level: Input 3.5~30V
Input resistance: 30K Ω
Output type: switch output, 4-channel (DO0~DO3). PNP output, with an output voltage equal to the power supplyvoltage and a maximum load current of 100mA, can directly drive intermediate relays. Communication: MODBUS TCP communication protocol
Web page: Supports web access module and web page setting module parameters. Interface: 2 RJ-45 network interfaces. The data between two network ports can be freely exchanged. Working power supply:+8~32VDC wide power supply range, with internal anti reverse and overvoltage protectioncircuits
Power consumption: less than 2W

The WJ94 remote I/O module can be used to measure eight switch signals and has four switch outputs. 1, Switching signal input and output
8-channel switch signal input, capable of connecting dry and wet contacts. Please refer to the wiring diagramfordetails; 4-channel switch signal PNP output, with an output voltage equal to the power supply voltage andamaximum output current of 100mA. Be careful not to overload the output, otherwise it will burn out the output
channel. 2, Communication Protocol
Communication interface: 2 RJ-45 network interfaces. Each network port has two indicator lights. After thenetwork cable is plugged in, the Link light (green light) will flash continuously, and the Data light (yellowlight)will flash irregularly. The data between two network ports can be freely exchanged. Communication protocol: Adopt Socket free protocol or MODBUS TCP protocol to achieve industrial Ethernet dataexchange. You can also access the control module directly through the webpage. Network cache: 2K bytes (for both sending and receiving)
Communication response time: less than 5mS. 3, anti-interference
There is a transient suppression diode inside the module, which can effectively suppress various surge pulsesandprotect the module
