National Instruments 777318-102 Analog Voltage Input Module

Part Number 777318-102  is the identifying part number for the National Instruments cFP-AI-102 Analog Voltage Input Module. The 777318-102 features 8 analog input channels that are connected to a successive approximation-type ADC having a resolution of 12 bits. The update rate on all channels is 360 Hz, corresponding to a period of 2.8 ms. The input signal ranges are software-selectable by channel and may take values like 0 to 20 V, 0 to 60 V, 0 to 120 V, or ±20 V, ±60 V, or ±120 V. The effective resolution and offset error depend on these ranges. Furthermore, the input impedance is 1.0 MΩ while the input noise is 7 mV + 1 LSB peak-to-peak. Moreover, the signal input bandwidth is 170 Hz. 

The 777318-102 draws 400 mW of power from the network module. The maximum isolation voltage between the channel and the ground is 250 Vrms and falls under Installation Category II. There is no isolation between the channels. The 777318-102 features two green LED indicators: POWER and READY. The POWER indicator lights up when you insert the module into a terminal base or a backplane and apply power to the connected network module. On the other hand, when the network module recognizes the connected voltage input module and sends the configuration information, the READY indicator lights up after the configuration is received. Furthermore, the module is also hot-swappable, meaning it can be installed on a powered terminal base without disturbing the operations of other devices. 

The recommended temperature range for the operation of the 777318-102 is -40 °C to 70 °C  at a relative humidity of up to 10% to 90%. On the other hand, it can be stored at –55 °C to 100 °C. Note that the device is designed only for indoor use and must be mounted inside a sealed enclosure for outdoor use. Furthermore, the device should be operated within a maximum altitude of 2000 m. The device meets the following safety standards for electrical equipment for measurement, control, and laboratory use: IEC 61010-1, EN 61010-1, UL 3121-1, UL 61010C-1, and CAN/CSA C22.2 No. 1010.1.
