Product Description 8-way DI high-speed counter, 8-way DO supports PWM output, Modbus TCP module WJ93 Product Overview: The WJ93 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. Sensor data can be forwarded to the network, or data from the network can be forwarded to the sensor. The WJ93 series products include power conditioning, switch quantity acquisition, transistor output, and RJ-45 network interface communication. The communication method adopts MODBUS TCP protocol. TCP is a transport layer based protocol that is widely used and a reliable connection oriented protocol. Users can directly set module IP addresses, subnet masks, etc. on the webpage. Can be used for monitoring and controlling the operation of sensor devices.Product model:WJ93- RJ45Communication interfaceRJ45: Output as RJ-45 network interfaceCompany ProfileShenzhen Weijunrui Technology Co., LtdSince: 2011Specialty: The company's main products include analog acquisition modules, signal isolators/conversion modules, and signal transmittersCapacity: Produce 10000 per monthAdvanced Features:Switching to TCP/network/remote IO module, Modbus RTU to TCP, RS232/485 to Ethernet, analog signal (current/voltage/thermistor/frequency/displacement/speed/pulse) isolation transmitter, mV differential signal amplifier, isolation amplifier, micro power DC-DC module power supply, etc WJ93General Parameters: Function Introduction (Typical @+25 ℃, Vs is 24VDC) Input type: switch input, 8 channels (DI0~DI7). Low level: Input<1V High level: Input 3.5~30V Frequency range 0-20KHz Counting range 0-0xFFFFFFFF Input resistance: 30K Ω Output type: open collector output, voltage 0~30V, maximum load current 30mA, 8 channels (DO0~DO7)To achieve a desired level output, an internal pull-up resistor with a resistance of 3K ohms can be turned on. PWMfrequency 1~65535Hz, duty cycle 0%~100% Communication: MODBUS TCP communication protocol Webpage: Supports web access module and web page setting module parameters. Interface: RJ-45 network interface. Working power supply:+8~32VDC wide power supply range, with internal anti reverse and overvoltage protection circuits Power consumption: less than 1W Working temperature:-45~+80 ℃ Working humidity: 10~90% (no condensation) Storage temperature:-45~+80 ℃ Storage humidity: 10~95% (no condensation) Isolation voltage resistance: non isolated Dimensions: 120mm x 70mm x 43mm The WJ93 remote I/O module can be used to measure eight switch signals and has eight switch outputs. Can be used as an 8-channel counter or 8-channel frequency measurement, It can also output 8 PWM signals. 1,Switching signal input and output 8-channel switch signal input, capable of connecting dry and wet contacts. Please refer to the wiring diagram for details; 8-channel switch signal output with open collector output, or internal pull-up output. 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 after the network cable is plugged in, and the Data light (yellow light) will flash intermittently. Communication protocol: MODBUS TCP protocol is adopted to achieve industrial Ethernet data exchange. 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 10mS. 3,anti-interference There is a transient suppression diode inside the module, which can effectively suppress various surge pulses and protect the moduleFAQQ: How to contact you?A: Please contact us via email or online customer service
