CD522 encoder module
The CD522 module offers accuracy and dynamic fexibility for a customized solution. It has two independent encoder inputs onboard and is easily
confgured using the Automation Builder software for 10 different operation modes and for frequencies up to 300 kHz (depending on CPU cycle
time). The CD522 module also integrates outputs for pulses and for PWM as well as normal inputs and outputs, depending on selected encoder
mode.
