Technical data

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

Type CD522-XC
Functionality
Digital inputs/outputs 24 V DC, dedicated inputs/outputs can be used for specific counting functions.
All unused inputs/outputs can be used as input/output with standard
specification.
Input options Catch/Touch operation, counter value stored in separate variable on external
event (rising or falling)
Set to preset counter register with predefined value
Set to reset counter register
End value output Output set when predefined value is reached
