National Instruments 780340-01 Multifunction Reconfigurable I/O Module

The National Instruments 780340-01 (or PXI-7852) is a high-performance Multifunction Reconfigurable I/O Module from the R-series. This module features a user-programmable Virtex-5 LX50 FPGA that provides flexibility for on-board processing and direct control over I/O signals. The FPGA offers 28,800 flip-flops, 28,800 6-input LUTs, and 48 DSP48 slices. It is ideal for applications like custom protocol communication, hardware-in-the-loop testing, high-speed control, and sensor simulation.

The 780340-01 includes eight analog input channels with a ±10 V input range. It offers 16-bit resolution and a maximum sampling rate of 750 kS/s per channel. Each channel uses a successive approximation ADC that offers independent timing and triggering for multirate sampling. The inputs are protected against overvoltage (up to ±42 V when powered on) and have a high input impedance of 10 GΩ in parallel with 100 pF. Output characteristics feature eight single-ended voltage output channels with a ±10 V range. The output channels also offer 16-bit resolution and capable of 1 MS/s maximum update rate.

This NI 780340-01 module operates through a PXI interface that supports master and slave configurations. This RIO module uses DMA, interrupts, or programmed I/O for data transfer. It includes three DMA channels for efficient data handling. The digital I/O section comprises 96 channels that are compatible with TTL. Each digital I/O section is configurable with programmable power-on states and capable of sourcing and sinking 4.0 mA.

The power requirements for this 780340-01 RIO module are diverse: 136 mA at +5 VDC, 604 mA at +3.3 VDC, 0.5 A at +12 VDC, and 0.25 A at -12 VDC. This module offers exceptional protection features that include short-circuit protection for voltage outputs and the ability to handle input voltages within ±12 V of ground. Dynamic characteristics include a 1 MHz small signal bandwidth and -80 dB crosstalk.

The 780340-01 weighs only 152 g and measures 16 cm by 10 cm in size. It operates in temperatures from 0 °C to 55 °C and can withstand storage temperatures from -20 °C to 70 °C. Safety and compliance standards include IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1.
