I-87088W-G CR

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. I-87088W-G CR has 8 PWM output channels and 8 digital inputs. It can be used to develop powerful and cost effective analog control system.
