Product DescriptionTwo PWM duty cycle signals converted to RS485, Modbus RTUmoduleWJ152Product features: Measure PWM conversion to standard Modbus RTU protocol At the same time, it can measure the frequency of PWM Support measuring the phase difference between two PWM circuits Wide power supply range: 8~32VDC High reliability, easy programming, and easy application Standard DIN35 rail installation, convenient for centralized wiring Users can program module addresses, baud rates, etcTypical applications: Motor PWM signal measurement Measurement of PWM signal for servo motor PLC signal measurement Frequency detection of PWM Intelligent factory and industrial Internet of Things PWM signal is transmitted remotely to the industrial computerProduct selection:WJ152 - Communication interface485: Output as RS-485 interfaceSelection example: Model: WJ152-485 indicates an RS-485 interface for outputCompany 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, etcWJ152 General Parameters:Function Introduction:(Typical @+25 ℃, Vs is 24VDC)Input type: 2-channel PWM signal input. Low level: Input<1VHigh level: Input 3.5~30VPWM frequency range 0-10KHz. Input resistance: 30K ΩCommunication: RS-485 standard character protocol and MODBUS RTU communication protocolBaud rates (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be selected by softwareThe address (0-255) can be selected by softwareCommunication response time: 100 ms maximumWorking power supply:+8~32VDC wide power supply range, with internal anti reverse and overvoltage protectioncircuitsPower consumption: less than 1WWorking temperature: -45~+80 ℃Working humidity: 10~90% (no condensation)Storage temperature: -45~+80 ℃Storage humidity: 10~95% (no condensation)Dimensions: 106 mm x 59mm x 24mmThe WJ152 remote I/O module can be used to measure 2 PWM signals. 1, Signal input2-channel PWM signal input, can be connected to dry contacts and wet contacts, and the input type canbesetthrough commands. 2, Communication ProtocolCommunication interface: 1 standard RS-485 communication interface. Communication Protocol: Supports two protocols, the character protocol defined by the command set andtheMODBUS RTU communication protocol. The module automatically recognizes communicationprotocols and can achieve network communication with various brands of PLCs, RTUs, or computermonitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. No verification. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) canbeset;The communication network can reach a maximum distance of 1200 meters and is connectedthroughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3, anti-interferenceParity check can be set as needed. There is a transient suppression diode inside the module, which caneffectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppresspowerfrequency interference from the power grid.FAQQ: How to contact you?A: Please contact us via email or online customer service
