NI does not recommend the sbRIO-9631 for new designs; use sbRIO-9627/9637 devices instead.
The sbRIO-9631 embedded control and acquisition device integrates a real-time processor, a user-reconfigurable FPGA, and I/O on a single printed circuit board. It features a 266 MHz industrial processor, a 1M gate Xilinx Spartan FPGA, 110 3.3 V (5 V tolerant/TTL compatible) digital I/O lines, 32 single-ended/16 differential 16-bit analog input channels at 250 kS/s, and four 16-bit analog output channels at 100 kS/s. It also has three connectors for expansion I/O using board-level NI C Series I/O modules. The sbRIO-9631 offers a -20 °C to 55 °C operating temperature range along with a 19 VDC to 30 VDC power supply input range. It provides 64 MB of DRAM for embedded operation and 128 MB of nonvolatile memory for storing programs and data logging.
This device features a built-in 10/100 Mb/s Ethernet port you can use to conduct programmatic communication over the network and host built-in web (HTTP) and file (FTP) servers. You can use the RS232 serial port to control peripheral devices.
The sbRIO-9631 is designed to be easily embedded in high-volume applications that require flexibility, reliability, and high performance. Single-Board RIO is sold only in OEM quantities. CompactRIO systems are ideal for low- to medium-volume applications and rapid prototyping.
