National Instruments cRIO-9101 CompactRIO Chassis

The National Instruments cRIO-9101 (Part Number: 779052-01) is a 4-Slot, CompactRIO Chassis. This rugged Chassis can be used to add multiple C Series I/O modules to an existing monitoring or control application. Users can program this Chassis through scan mode for a quick expansion of their real-time infrastructure or through the onboard FPGA.

The reconfigurable FPGA incorporated in this Chassis has 5120 logic slices and 81,920 bytes of embedded RAM. The addition of this FPGA enables the cRIO 9101 to offer high-speed control and I/O. To communicate with the C Series modules installed in any of the four slots, a CompactRIO Controller is necessary. If the user wants to mount this Chassis on a DIN rail, then they can acquire the National Instruments 9912 DIN rail kit separately. The other possible mounting options are rack mounting and panel mounting.

 The NI cRIO-9101 weighs around 490 g and draws 500 mW of power from +5 VDC and 1,800 mW of power from +3.3 VDC rail. Thus, the total power required (maximum) for operating this Chassis is 2,300 mW. To start using the CompactRIO system, a Windows computer with NI-RIO drivers is required. In this Chassis, each I/O module maintains an individual connection to the FPGA core at a precise synchronization of up to 25 ns resolution. This Chassis is considered the heart of any CompactRIO system since it comes with an I/O core. The NI cRIO 9101 allows the user to remove I/O modules with the power supply in the ON position without affecting the entire control system.
