Part Number: 778701-01
The National Instruments 778701-01 is a PCI-6723 Analog Output Device, designed to meet the demands of industrial automation applications through its high-performance features. This output module offers 32 analog voltage output channels, each with a resolution of 13 bits and a remarkable update rate of 800 kilo samples per second, ensuring efficient processing capabilities. The module supports a voltage output range of ±10 V, allowing for the generation of diverse signal amplitudes. It employs double buffered digital-to-analog converters to produce smooth output signals. With an output impedance of 0.1 Ω maximum and a driving current capacity of ±5 mA, this device delivers reliable performance. The accuracy of the 778701-01 is ±0.0377% of reading ± 7.010 mV, with a temperature drift of 0.0005% per degree Celsius, while its relative accuracy is up to ±2.0 LSB, and differential nonlinearity is within ±0.9 LSB, ensuring monetary behavior across its 13-bit resolution. The slew rate is 0.7 V/μs, indicating the responsiveness to input signal changes, complemented by a signal settling time of 45 μs, extending to a maximum of 55 μs. At mid-scale transitions, the module experiences a glitch energy of 400 mV for 2 μs and a channel-to-channel glitch of 100 mV for 1.2 μs. Additionally, it provides an external reference input range of ±11 V with overvoltage protection up to ±27 V under 12-volt operation. The 778701-01 includes 8 TTL/CMOS compatible digital I/O lines for control and signaling tasks, as well as two 24-bit timers/counters and a scaler for clock signal generation and edge detection. It operates on 3.3 Volts DC with a current draw of 300 mA or on 5 Volts with a 3 Ampere current draw. The module's compact design, measuring 17.4 cm × 9.8 cm (6.85 in. × 3.85 in.), facilitates easy installation and portability, making it an excellent choice for demanding control applications.
