X1 – X8: Encoder Feedback, Digital Quadrature
The Power Brick Controller accepts digital quadrature (also known as incremental) encoder signals by
default. It provides up to four counts per square cycle, and extends it using hardware-computed (ASIC)
1/T.

Quadrature encoders can be wired in and processed regardless of the
encoder feedback option(s) the Power Brick Controller is ordered
with.
The +5 VDC encoder power is limited to ~250 mA per channel. For
encoders requiring more current, the +5 VDC power can be alternately
brought in externally through the +5 VDC ENC connector.
Encoders requiring a voltage level other than +5 VDC (higher or
lower) should be powered up using an external power supply directly
into the encoder.
