Specifications
General Specifications
Performance Specifications
Note
The response time is the time between the moment the A, B, Z, or IN input
turns ON or OFF and the moment the digital output is updated to the new
state. The specified response time may not be achieved during monitoring or
maintenance.
I/O Signal Specifications
The encoder A and B inputs are phase differential signals for counting. The
encoder Z input is a zero marker each revolution.
