National Instruments 778971-01 PXI Digital I/O Module

Part number 778971-01 from National Instruments is the identifying part number for the PXI-6513 PXI Digital I/O Module. This module features 64 sink output channels, making it ideal for controlling and interfacing with various digital devices and systems. Operating the 778971-01 requires a power consumption of +5 volts DC with a current consumption of 250 mA and +3.3 VDC with a current consumption of 300 mA. The module supports various input voltage ranges including the input logic low voltage of ±4 Volts DC maximum and input logic high voltage ranging from ±11 to ±30 Volts DC. Its input current ranges from 4.5 mA at 11 V inputs to 12.5 mA at 30 V inputs with a propagation delay of 75 μs, typical.

Physically, this I/O module has a compact and lightweight design with dimensions of 21 cm × 13 cm (8.38 in. × 5.12 in.) and weighs 136 g (4.8 oz). The 778971-01 should only be operated in an environment with an ambient temperature between 0 degrees Celsius to 55 degrees Celsius and can withstand storage temperatures between -20 degrees Celsius to 70 Degrees Celsius with an operating relative humidity of 10% to 90% noncondensing and storage relative humidity of 5% to 95%, noncondensing for long-term use and reliability. This model can be mounted at a maximum altitude of 2000 meters with a pollution degree of 2 and is only intended to be used indoors where nonconductive pollution occurs. 

With operational shocks of 30 g peak, half-sine, and 11 ms pulse, as well as operating vibrations of 5 Hz to 500 Hz, 0.3 grms, and nonoperating vibrations of 5 Hz to 500 Hz, 2.4 grms, the PXI module is built to withstand demanding working circumstances.

The 778971-01 module has been tested and designed to meet safety standards following the IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1 for safety, making it suitable for use in measurements, control and laboratory use. This device does not feature an Ingress protection rating hence it should be installed in a dust and moisture-free environment.
