Product Overview:

Function Introduction:

The WJ152 product implements signal acquisition between sensors and hosts for measuring PWMsignals. TheWJ152 series products can be applied in RS-485 bus industrial automation control systems, automated machinetools, industrial robots, three coordinate positioning systems, PWM measurement, servo measurement, and more. The product includes signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication.Each serial port can connect up to 255 WJ152 series modules, and the communication method adopts ASCII codecommunication protocol or MODBUS RTU communication protocol. The baud rate can be set by code and canbehungon the same RS-485 bus as control modules from other manufacturers, making it easy for computer programming.The WJ152 series products are intelligent monitoring and control systems based on microcontrollers. All user set
configuration information such as address, baud rate, data format, parity status, etc. are stored in non-volatile memoryEEPROM. The WJ152 series products are designed and manufactured according to industrial standards, with no isolationbetween signal inputs/outputs, strong anti-interference ability, and high reliability. The working temperature rangeis-45 ℃ to+85 ℃.

The WJ152 remote I/O module can be used to measure 2 PWM signals. 1, Signal input
2-channel PWM signal input, can be connected to dry contacts and wet contacts, and the input type canbeset
through commands. 2, Communication Protocol
Communication 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-interference
Parity 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.
