National Instruments 780927-01 Voltage Output Module

National Instruments part number 780927-01 is the version of the NI-9264 Voltage Output Module with DSUB Connectors. These connectors prepare the module for use in high reliability applications in either CompactRIO or CompactDAQ systems. Equipped with 16 channels and a string DAC, the 780927-01 is ideal for a wide variety of measurement, communication, or control applications. The DAC resolution is 16 bits, helping to ensure precise analog output. When powered on, the channels remain in an 'off' state, with a startup and power-down voltage of 0V.

The 780927-01 offers reliable performance across an varied output range, achieving a maximum output of ±10.65 V and a minimum output of ±10.35 V. The typical output range of the 780927-01 lies between ±10.5 V with an output impedance of 2.0 Ω. Each channel of the module has a typical current drive of ±4 mA, and they can accommodate a maximum current drive of ±16 mA. 

The energy-efficient functionality of the 780927-01 is made evident through the module’s maximum power consumption of 1 W when in active mode, paired with a maximum power consumption of only 25 μW when in sleep mode. The thermal dissipation of the device, when under operational conditions at 70°C, sees the same power usage.

Protective features of the 780927-01 include indefinite resistance to short circuits, tolerance for overvoltage up to ±27 V at 25°C, and a low noise output of 500 μVrms. The module also features a variety of isolation properties, including no channel-to-channel isolation and a continuous channel-to-earth ground of 60 VDC.  These features ensure that the 780927-01 is able to be operated safely and reliably across various testing environments.
