National Instruments 779015-01 Analog Input Module 

National Instruments part number 779015-01 is an identifying part number for the NI-9233, an Analog Input Module with 4 Analog Channels with 24 bits resolution and an Input Range of ±5 V. The module has a dynamic range of 102 decibels. It includes four analog input channels, numbered 0 to 3, labeled as AIx (where "x" is the channel number). These channels feature a BNC connector type interface. It is a C series device with a 12.8 MHz time base clock, which can be extracted only in single-cycle timed loop mode. 

It features built-in start and stop channels that allow the user to control data acquisition. The module also supports TEDS read/write capability and includes a USB interface with integrated signal conditioning, meeting various testing requirements. The NI 779015-01 Module complies with various industrial safety specifications and features AC input coupling. It provides excellent accuracy for the internal master time base, with a precision of ± 100 ppm. It consumes up to 620 mW when active and a maximum of 0.5 mW in sleep mode. This Analog Input Module features an IEPE excitation current with a minimum of 2.0 mA and a typical value of 2.2 mA. 

It has a maximum IEPE compliance voltage of 19 V. The module provides overvoltage protection with respect to chassis ground. For an IEPE sensor connected to AI+ and AI–, the protection range is ±30 V. For a low-impedance source connected to AI+ and AI–, the protection range is –6 to 30 V. The 779015-01 operates within a temperature range of –40 to 70 °C and can be stored at temperatures between –40 and 85 °C. It supports non-condensing humidity levels of 10 to 90% RH during operation and 5 to 95% RH during storage. This compact and lightweight module measures 140.66 mm in length, 88.12 mm in width, and 25.34 mm in depth, with a weight of 6.1 oz.
