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. CAN-2088D is a PWM slave module of DeviceNet protocol. It has 8 PWM output channels and 8 high speed counter channels. It can be used to develop powerful and cost effective analog control system.
