National Instruments 781030-02 C Series Digital Module

Part number 781030-02 from National Instruments describes the version of the NI-9375 C Series Digital Module with DSUB connectors that is conformal coated. These connectors allow the module to connect with devices from both CompactDAQ and CompactRIO series, while the conformal coating adds an extra layer of protection- guarding the device against environmental elements that may cause damage. 

Screw flanges are used to secure the DSUB connectors to the 781030-02. They are tightened with a recommended torque of 0.2 N·m (1.80 lb·in.). With 16 digital input and 16 digital output channels, the 781030-02 offers a total of 32 digital channels that are compatible with logic levels of 24. Depending on the kind of external power supply that is utilized, the module can handle digital output signals ranging from 6 to 30 volts. 

In terms of environmental characteristics, the 781030-02 has a specified Pollution Degree of 2. It is designed to operate effectively in a variety of environments, remaining functional at altitudes even up to 5,000 m. With operating vibration, the 781030-02 can withstand random vibrations at 5 g RMS within the frequency range of 10 Hz to 500 Hz, and it can withstand sinusoidal vibrations at 5 g over the same frequency range. In addition, the robust digital module can resist operating shocks of 30 g for an 11 ms half sine wave and 50 g for a 3 ms half sine wave. These features collectively contribute to the ability of the 781030-02 to function effectively in diverse conditions.

The 779801-02's operational temperature lies within a range of -40 °C to 70 °C (-40 °F to 158 °F). The module may be safely stored in a temperature range between -40 °C and 85 °C (-40 °F and 184 °F).
