National Instruments PXIe-7857R PXI Multifunction Reconfigurable I/O Module

The PXIe-7857R (Part number: 784146-01) is a Multifunction Reconfigurable I/O Module created by National Instruments. This model offers a combination of analog and digital I/O channels in a single device. The PXIe-7857R features the flexibility of system timing and supports synchronization. An FPGA chipset is installed in the PXIe-7857R. This module is customizable with the FPGA module. The PXIe-7857R can perform individual triggering and timing on all channels. A separate ADC is featured on each channel for this purpose. This feature also supports multi-rate sampling for different channels. This module can interface with other PXI Express devices and can directly transfer the data to these devices.

The PXIe-7857R Multifunction Reconfigurable I/O Device provides 8 AI channels. The input channels feature a SAR ADC. The ADC resolution of the module is 16 bits. The PXIe-7857R can sample data at a maximum rate of 1 MS/sec. This model supports different voltage range options for input signals. The supported ranges are +10 V, +5 V, +2 V, and +1V. The device can sustain up to +42 V without getting damaged. The PXIe-7857R also features eight single-ended AO channels. The output type of these channels is voltage. The PXIe-7857R can update the AO channels at a rate of 1 μs. The impedance of the AO channels is 0.5 Ω. The AO channels have protection up to ­+15V. 

The PXIe-7857R device incorporates 48 DIO channels. These channels are compatible with the TTL and CMOS family. The digital channels of the PXIe-7857R are individually programmable. The DIO channels also support five programmable logic levels.
