This product is RoHS-compliant

Please contact us if you require a non-RoHS version.

Please note, Acces I/O products are often available in an array of different options, of which only a selection will be displayed here. Please contact us for pricing if you require a product option that is not shown on our website.

The M.2-QUAD-8 consists of a 2260/2280 sized M.2 Card with B & M keys and latching I/O connectors that connects to two DB-37F Modules via included 9 cables. The M.2-QUAD-4 consists of a 2260/2280 sized M.2 Card with B & M keys and latching I/O connectors that connects to one DB-37F Module via an included 9 cable. 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
• The M.2-QUAD products are well suited for use in industrial and embedded environments and factory locations.
