M-7088

8-Channel PWM Isolated Output and 8-Channel High Speed Counter Digital Input Module (Frequency), communicable over RS-485 and Modbus RTU, with Voltage Input

  Price:  $299.00  

Features

M-7088 has 8 PWM output channels and 8 counter inputs. It can be used to develop powerful and cost effective analog control system. PWM (Pulse width modulation) is a powerful technique for controlling analog circuits. It uses digital outputs to generate a waveform with variant duty cycle and frequency to control analog circuits. It can be used to Controlling the position/speed of motors, Dimming the brightness of lamps, Controlling the speed of fans… etc.

Features

  • Automatic generation of PWM outputs by hardware, without software intervention.
  • 10Hz ~ 500KHz PWM output frequency with 0.1%~99.9% duty cycle
  • Software and hardware trigger mode for PWM output
  • Individual and synchronous PWM output
    Using software trigger mode, you can set configuration for all PWM channels then trigger them one by one or all of them at the same time.
  • Burst mode PWM operation for standby
  • DI channel can be configured as simple digital input channel or hardware trigger source of the PWM output.

Applications

  • Controlling the position/speed of motors
  • Dimming the brightness of lamps
  • Controlling the speed of fans
