QD8
Tech Specs:
With dimension of 3.6×2.3 inches, the QD8 is an expansion board for a TERN controller. The QD8 adds up to 8 quadrature decoders(HCTL2020 or HCTL2021) and 6 16-bit hardware counters(82C54, can be used to count Index pulses).
The quadrature decoder allows the host controller to interface to a quadrature encoder, used to generate position pulses in a closed loop motion control application. The QD8 interfaces to a TERN controller via 8-bit high speed data bus using J1 and J2 headers.
- Up to 8 Quadrature Decoders and 6 Index Counters
- 8-bit parallel high speed bus to TERN controller
- 3.6×2.3 inches, 5V
