Motor or fan speed measurement and PWM speed control module RS485 communication WJ155
Product features:
Motor speed measurement to standard Modbus RTU protocol
Output a PWM signal that can be used to control the motor speed
Speed pulse input supports PNP and NPN inputs
Automatically measure the pulse frequency of the input
The number of pulses per revolution of the motor can be set to automatically convert the speed
The frequency and duty cycle of PWM can be set through the RS-485 interface
Wide power supply range: 8~32VDC
High reliability, convenient programming, and easy application
Standard DIN35 rail installation for convenient centralized wiring
User programmable module address, baud rate, etc
Typical applications:
Measurement and control of industrial four line fans
Air conditioning fan control
Motor measurement and control
Servo control
Measurement of proximity switch pulse signals
Remote transmission of speed signal to industrial computer
Intelligent factories and industrial Internet of Things
Product Overview:
The WJ155 product realizes signal acquisition between sensors and the host, used to collect motor speed and control PWM motors. WJ155 series products can be applied
In the RS-485 bus industrial automation control system, automated machine tools, industrial robots, three coordinate positioning system, displacement measurement, stroke measurement, angle measurement
Measurement, speed measurement, flow measurement, product counting, and so on.
The product includes signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ155 series modules,
The communication method adopts ASCII code communication protocol or MODBUS RTU communication protocol, and the baud rate can be set by the code, which can be hung with control modules from other manufacturers
On the same RS-485 bus, it is convenient for computer programming.
The WJ155 series products are intelligent monitoring and control systems based on microcontrollers, with all user set addresses, baud rates, data formats, and parity calibration
The configuration information such as verification status is stored in the non-volatile memory EEPROM.
The WJ155 series products are designed and manufactured according to industrial standards, with no isolation between signal inputs/outputs, strong anti-interference ability, and high reliability. Working temperature
Temperature range -45 ℃ to+85 ℃.
