Features

The I-7088 has 8 PWM output channels and 8 counter inputs and can be used to develop powerful and cost effective analog control systems. PWM (Pulse width modulation) is a powerful technique for controlling analog circuits that uses digital outputs to generate a waveform with variant Duty Cycle (The fraction of time that a system is in an "active" state) and frequency to control analog circuits and can be used to control the position/speed of motors, dim the brightness of lamps, control the speed of fans, etc.

The I-7088 will also automatically save the counter value to EEPROM if the power supply is interrupted or lost.

  • Automatic hardware generation of PWM outputs without software intervention
  • 1Hz ~ 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 the configuration for all PWM channels then trigger them individually or all of them at the same time.
  • Burst mode PWM operation for standby
  • DI channel can be configured as either a simple digital input channel or a hardware trigger source for the PWM output.

Applications

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