Details
The mPCIe-QUAD-8 consists of a type F1 PCI Express Mini Card (mPCIe) interface board that connects to two DB-37F Modules via included 9” cables. The modules are designed to be easily panel-mounted in any application environment, and have convenient mounting holes for non-panel-mount applications. Up to eight differential (or single-ended) encoders (each with A, B, and Index) can be monitored simultaneously. Type ISL32173 differential input circuits provide compatibility with a wide variety of quadrature encoder outputs. The LSI/CSI LS7766 features:- 32-bit quadrature counters support x1, x2, and x4 counting modes, or can be used as non-quadrature up/down counters
- Quadrature frequencies up to 9.6MHz
- 4.5MHz when powered with 3.3VDC
- Non-quadrature frequencies up to 40MHz when powered with 5VDC
- 20MHz when powered with 3.3VDC
- Programmable index and marker flags (carry, borrow, sign & compare)
- Enable/disable sources generating IRQ’s
- Programmable count modes:
- Normal (free-run) / Modulo-N / Range Limit / Non-Recycle, Binary / BCD
