National Instruments 777318-102

The National Instruments 777318-102, also known as the cFP-AI-102 Analog Voltage Input Module, is a robust device designed for precise analog data acquisition. This module features eight analog input channels, each connected to a high-performance successive approximation ADC with a resolution of 12 bits. With an update rate of 360 Hz, corresponding to a period of 2.8 milliseconds, it effectively captures dynamic signals. Input ranges are software-selectable on a per-channel basis, accommodating configurations such as 0 to 20 V, 0 to 60 V, 0 to 120 V, and ±20 V, ±60 V, or ±120 V, with effective resolution and offset error contingent upon the selected ranges. The input impedance is specified at 1.0 MΩ, with input noise measuring at 7 mV + 1 LSB peak-to-peak. The module offers a signal input bandwidth of 170 Hz and operates with a power draw of 400 mW from the connected network module.

The 777318-102 ensures maximum isolation voltage of 250 Vrms, compliant with Installation Category II, though it does not provide isolation between channels. It features dual green LED indicators—POWER, which illuminates upon successful insertion into a terminal base, and READY, which lights up when configuration data is recognized by the network module. The module is also designed for hot-swapping capabilities, allowing installation on a powered terminal base without affecting ongoing operations. Operating temperature ranges from -40 °C to 70 °C with a relative humidity of 10% to 90%, while storage conditions can withstand temperatures ranging from -55 °C to 100 °C. The 777318-102 is intended for indoor use only and should be housed within a sealed enclosure for outdoor applications, with a maximum operational altitude of 2000 meters. It adheres to critical safety standards, including IEC 61010-1, EN 61010-1, UL 3121-1, UL 61010C-1, and CAN/CSA C22.2 No. 1010.1, ensuring reliable performance in various measurement, control, and laboratory environments.
