National Instruments sbRIO-9476 C Series Digital Module

The National Instruments sbRIO-9476 (Part Number: 783951-01) is a 500 µs, 32-Channel Digital Module from the C Series. This module supports hot-swapping and has a D-SUB front connector. Each channel of the NI sbRIO-9476 can work with signals ranging in between 6 V and 36 V, as determined by the external power supply. This module offers a comprehensive range of protective features. The 32 digital output channels are designed to operate as sourcing outputs at a maximum achievable update rate of 500 µs.

This C Series Digital Module comes equipped with a 37-pin D-SUB connector that provides access to all the digital output channels. The National Instruments sbRIO-9476 C Series Digital Module has current sourcing outputs. Thus, the digital output pin of the relevant channel is driven to Vsup when the associated channel is turned on. The NI sbRIO-9476 allows direct connectivity with a broad range of industrial devices including solenoids, lamps, motors, valves, actuators, etc. These devices, along with others, are widely used in manufacturing and industrial environments. 

Each channel included in this C Series Digital Module can provide up to 250 mA of current on a continuous basis. However, you can connect multiple channels in parallel for applications where a higher output current is required. The NI sbRIO-9476 module comes with integrated protective circuitry that protects the module from current and voltage surges resulting from short circuits. Excessive flow of current from any DO causes the relevant channel to go into a protective state.
