These PCI Express Mini cards feature a selection of digital I/O functions for compact control and monitoring applications. Choose up to 24 channels offering various voltage, isolation, speed, and counter/timer options and can integrate additional I/O functions in systems without board modifications or customization. This \ design provides system integrators numerous off-the-shelf I/O configurations for new and existing embedded systems.

All ACCES mPCIe cards offer latching connectors for shock and vibration mitigation as well as an operating temperature of -40°C to +85°C. The cards have been designed for use in environments such as military and defense along with applications such as health and medical, point of sale systems, kiosk design, retail, hospitality, automation, gaming and more. The size (50.95mm x 30mm) allows for performance in applications where space is a valuable resource.

The Digital Integration line of cards encompasses a wide variety of digital I/O types, including:

  • 24 channels of 3.3V LVTTL (optional 5V TTL) high-current digital I/O
  • 4, 8, or 16-channel optically-isolated inputs at up to 31VDC or VAC RMS
  • 4 or 8-channel solid state (FET) or electromechanical relays
  • 4 or 8-channel 32-bit counters supporting both pulse and quadrature signals

All the cards share features such as memory mapped registers for low-latency operation. Output channels support pulse/train / PWM / frequency / and quadrature generation. Input channels support quadrature encoders, flexible measurement of pulse duration, frequency, and event counting, with optional debouncing, IRQ generation, and more.
