Yes. Note also the existence of

Can these cards also accept Absolute Encoders?
Not directly, and it rather depends on what type of absolute encoder it is and what protocol it uses.
Do you already have the motors and drives?
Resolvers are one type of absolute encoder that requires special hardware. Both Pico and Mesa make suitable interfaces. I am not sure that they are still absolute when used with the Pico quadrature convertor. They still are with the mesa 7i49, but that is not compatible with the 5i25, you would need a 5i20 or 5i23 (or 7i43)
