National Instruments 778965-01 PXI Digital I/O Module

The part number 778965-01 from National Instruments is the identifying part number for the PXI-6514 PXI Digital I/O Module. This Digital I/O module features 32 optically isolated 2 source/sink inputs as well as 32 optically isolated 2 sink outputs. The module requires 5 volts DC to operate with a current consumption of 250 mA. It can handle a maximum switching voltage of 30 Volts DC. The module can support signals of different voltage levels with 0 VDC to ± 4 VDC for low-level signals and ± 11 VDC to ± 30 VDC for high-level signals. 

The 778965-01 input channels can handle a maximum current draw of 4.5 mA at 11 Volts and 12.5 mA at 30 Volts with a typical propagation delay of 75 μs allowing it to acquire data signals quickly for time-sensitive applications. The outputs are equally capable, with a typical propagation delay of 80 μs when loaded with a 100 Ω resistor, and they feature programmable power-up states to ensure safe and predictable operation during startup. 

This I/O module has a compact and lightweight design with dimensions of 16 cm by 10 cm and weighing 172.9 grams making it portable as well. The module should only be operated in an environment with an ambient temperature between 0 degrees Celsius and 55 degrees Celsius and can withstand storage temperatures between -20 degrees Celsius to 70 Degrees Celsius for long-term use and reliability. The 778965-01 has an operational shock rating of 30 g peak, half-sine,11 ms pulse (tested in accordance with IEC-60068-2-27 and a test profile developed in accordance with MIL-PRF-28800F).

778965-01 has been tested and designed to meet safety standards in accordance with the IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1 for safety, and EN 61326, IEC 61326, EN 55011, CISPR 11, AS/NZS CISPR 11, FCC 47 CFR Part 15B, and ICES-001 for EMC. Make sure to mount this module at an altitude of 5000 meters maximum above sea level. The instrument does not feature and Ingress protection rating hence it should be installed in a dust and moisture-free environment.
