National Instruments 782352-01 Counter/timer Module 

National Instruments part number 782352-01 is an identifying part number for the PXIe-6612  a PXI Timer/Counter Module with 40 DIO Channels and 51 kΩ pull down resistance. The NI 782352-01 excels in a range of applications including encoder position measurement, event counting, period measurement, pulse-width measurement, pulse generation, pulse-train generation, and frequency measurement. It is equipped with eight counter/timers, digital debouncing filters, and TTL/CMOS-compatible digital I/O. 

Additionally, the part number 782352-01 supports three simultaneous high-speed DMA transfers, ensuring efficient and reliable data processing. This module features eight counters/timers, each with a resolution of 32 bits. These counters support a variety of measurements including frequency, edge counting, pulse, pulse-width, semi-period, period, and two-edge separation. This versatility makes this device ideal for a wide range of precise timing and counting applications. This module offers a total of 40 channels, distributed across Port 0 (P0.<0..31>) and Port 1 (P1.<0..7>), or PFI <0..39>. 

Each channel is referenced to ground (GND) and can be individually programmed as either input or output, providing flexible direction control. Each channel features a 51 kΩ pull-down resistor to ground, ensuring stable operation. The input voltage protection for these channels ranges from -3 V, safeguarding the module from voltage spikes. The 782352-01supports up to 32-bit port/sample sizes, has a 75 Ω output impedance, and allows each terminal to be programmed as input or output. Data transfers are handled via DMA (scatter-gather) and programmed I/O methods, ensuring efficient and flexible connectivity and data management.
