    Description

    The product features part numbers 779003-01 and 783908-01, designed to seamlessly integrate with CompactDAQ and CompactRIO platforms. It offers 8 digital output channels, catering to a variety of digital I/O requirements with logic levels set at 12 V and 24 V.

    For enhanced safety, each channel is isolated from Earth with a 250 Vrms, CAT II rating. The device can handle output capacities ranging from 5 VDC to 30 VDC, and boasts a maximum update rate of 1 us, ensuring rapid response times for critical applications.

    Users have the option to choose between screw terminal (779003-01) and spring terminal (783908-01) connectivity options, based on their specific wiring preferences. However, it’s notable that the product is not conformal coated, which may influence the choice of deployment environment.

    For operational completeness, the NI-9927 Backshell Connector Kit is recommended for screw terminal configurations, whereas the NI-9981 Backshell Connector Kit is suggested for spring terminal configurations. This ensures a secure and reliable connection.

    The device’s output impedance lies between 0.07 Ω to 0.13 Ω, and it is capable of delivering a continuous output current of 1.0 A per channel. Moreover, transient overvoltage protection is robust, with a rating of 2,300 Vrms, providing an additional layer of security against unexpected voltage spikes.

    As for the physical aspect, the weight of the modules varies slightly depending on the terminal type: the screw terminal version weighs 5.3 oz, while the spring terminal version is slightly lighter at 4.9 oz.
