6 Channel Encoder Input Controller – CPCI323

The CPCI323 Quadrature Incremental Encoder Interface is designed to interface with up to six quadrature incremental encoders. This is an ideal solution for all applications where several encoders must be connected with a maximum of flexibility and a minimum of overhead.

This CompactPCI card is availabe in a 3U and a 6U form factor.


Executes local firmware from ROM or custom firmware downloaded by the host.
Mailbox with polling and/or host interrupt, local interrupt mechanism
Easy host interface, CPCI321/CPCI322 alike
32 bit counter for each encoder input
Index signals can be configured for detection of rising, falling or any edge
Index can be used to load the corresponding counter with a preset value
Counter value has one LSB uncertainty during movement and is accurate at ease
