I-7088-G CR ICP DAS Encoder Counter Frequency

• 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
• 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
• New Color

I-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.
