PCIe-6537B Request for Availability

National Instruments PCIe-6537B Digital I/O Device

The PCIe-6537B (Part Numbers: 782631-01, 153500A-03L) is an efficient Digital I/O Device designed by National Instruments. Equipped with 32 data channels, the PCIe-6537B features various options for digital inputs and outputs for PC-based systems. These channels can stream continuous data and boast per channel direction control. While the module does not have dedicated input or output channels, it does has six PFI channels. The total power of the PCIe-6537B is 6 W, and it draws in 1 A for +3.3 VDC and 225 mA for +12 VDC.

The sample timing types of the Digital I/O Device include Sample Clock, Change Detection, Handshake, Burst Handshake, and Pipelined Sample Clock. The triggering features of the PCIe-6537B include eight trigger channels that support both RTSI and PXI bus types. This device has a clock rate up to 50 MHz, and it generates signals of 2.5 and 3.3 volts. The maximum drive strength is +16 mA and +32 mA respectively. This device also has an onboard clock, with a frequency from 48 Hz to 50 MHz. The maximum toggling rate for the data channels is 25 MHz.

The PCIe-6537B Digital I/O Device supports NI-DAQmx driver software. The older versions of this software before version 9.6.1 are not supported. The NI-DAQ features a programming interface with various ADEs. Supported application software types are NI LabVIEW, NI LabWindows, and Microsoft Visual Studio.

Physically, the device measures dimensions of 7.13 in. × 0.85 in. × 4.93 in. (18.1 cm × 2.2 cm × 12.6 cm) and it weighs 3.8 oz (107.7 g). When being used, the operational temperature range spans from 0 ºC to +45 ºC. When not in use, the storage temperature range of the device is -20 ºC to +70 ºC. The relative humidity is noncondensing, and it ranges from 10% to 90% when operational and 5% to 95% when in storage. The environmental specifications of the PCIe-6537B meets IEC 60068-2-56 standards.
