This manual introduces the hardware configuration, functionality, address addressing, input selection, voltage and current range selection and usage methods of PC/104 embedded PC isolated industrial analog I/O series cards
The MSI-P416 is an isolated 16‑bit analog input card designed for harsh electrical environments in PC/104 embedded systems. It provides two isolated channels with selectable voltage or current ranges, bipolar or unipolar operation, and on‑board surge suppression, making it suitable for battery charging, RTU, SCADA, and industrial monitoring applications.
The hardware features a 4‑layer CMOS design, an Analog Devices AD7715 16‑bit sigma‑delta A/D converter per channel, and an AD780 voltage reference with 3 ppm/°C drift. Addressing is 16‑bit I/O‑mapped via jumpers JP1, and the card operates from –40 °C to 85 °C. Programming registers (C, S, T, D) allow configuration of input ranges, gains, and calibration.
