ACCES I/O Products announces the release of the mPCIe-DAAI16-8F, a high-performance PCI Express Mini Card (mPCIe) multifunction analog output/input module that delivers 16-bit precision, simultaneous analog output and input, and flexible digital I/O – all in a small, rugged design ideal for embedded and OEM applications.
The mPCIe-DAAI16-8F integrates eight 16‑bit analog outputs supporting both voltage and current outputs, ideal for applications that need 4-20mA control. In addition to the flexible DAC outputs, eight 16-bit analog input channels, software‑selectable as eight single-ended or four differential inputs, are included. An aggregate analog‑input sampling rate up to 1MSPS supports dynamic measurements, while each DAC channel can perform hardware-paced waveform playback up to 125kSPS per channel simultaneously. A compact, double-stack mPCIe Type F1 form factor with latching I/O connectors enables reliable operation in shock and vibration-prone environments.
Factory options include extended temperature of -40°C to +85°C, current inputs (4-20mA, 10-50mA), voltage dividers for higher voltage inputs, and HART modem capability. Additional customisation options include conformal coating, custom software / product-labelling, and more – even entirely new features customised to specific needs, enabled by advanced FPGA-based design.
Key features of the mPCIe-DAAI16-8F family include:
- PCI Express Mini Card (mPCIe) Type F1 (full length) with high-retention latching connectors vs shock/vibration
- Eight 16‑bit analog outputs with software selectable current (4-20 mA, 0-20 mA, 0-24 mA) and voltage ranges
- Hardware‑paced DAC waveform streaming up to 125kSPS per channel using onboard FIFO + DMA architecture
- Eight 16‑bit analog inputs – software‑selectable as eight single ended or four differential; up to 1MSPS aggregate ADC rate
- Seven per‑channel programmable differential, bipolar input ranges
- Eight digital I/O pins (four inputs, four outputs) can be used for triggering, status, or control and optional digital integration features (pulse/PWM generation and measurement, edge-specific IRQs and counting)
- Flexible A/D triggering – start sources include software, internal timer, external start, and externally triggered timer start for precise synchronisation
- Onboard watchdog with status output
- Factory options: HART modem (on DAC #0), 4-20 mA / 10-50 mA ADC inputs, per-channel input voltage dividers, conformal coating, and more.
- Made in the USA; RoHS compliant
All ACCES mPCIe (and M.2) cards offer high retention latching connectors for shock and vibration mitigation as well as an optional extended operating temperature of -40°C to +85°C. The small size (mPCIe Type F1: 30 x 50.95mm) allows for maximum performance in embedded applications where space is a valuable resource.
These cards are supported for use in most operating systems and include a free Linux and Windows compatible software package. This package contains sample programs and source code in C# and Delphi for Windows. Linux support includes installation files and samples for programming level via our open-source kernel driver. Third-party support includes a Windows standard DLL API library usable from most popular application programs. Embedded OS support includes the family of Windows Operating Systems, including IoT. ACCES also now offers a VxWorks driver/library for the ultimate real-time process monitoring and control solution.
