Description
The CompactRIO Chassis, identified by the part number 781316-01, is a remarkable piece of equipment designed for various applications. This model, known as the NI-9157, is a versatile and powerful chassis that supports a wide range of modules and accessories.
One of the standout features of the NI-9157 is its provision for 14 slots, which allows for extensive expansion and customization options to meet specific project requirements. It is powered by a Virtex-5 LX85 FPGA, ensuring robust performance and the ability to handle complex processing tasks efficiently.
The chassis interfaces through MXI-Express, enabling high-speed data transfer and seamless communication with other devices. It can support a maximum chain of 6 NI MXI-Express RIO models, with the capability to have up to 8 chains per controller. This flexibility makes it a suitable choice for large-scale applications requiring multiple devices to work in tandem.
For power-up options, users have the choice to either do not autoload VI or to autoload VI on device power-up, providing flexibility based on the application’s startup requirements. The power supply requirement is external, necessitating filtering and regulating to ensure stable operation.
The chassis features redundant pairs of V and C terminals for enhanced reliability and safety. It also has a preference for a higher voltage supply, optimizing its performance based on the available power sources. Additionally, integrated reverse-voltage protection safeguards the device against potential damage caused by incorrect power supply connections.
An available NO FPGA APP switch adds another layer of control, offering users the ability to manage the FPGA application directly. The chassis is equipped with 1 power LED and 3 user FPGA LEDs, with the power LED displaying colors green (V1) and yellow (V2) to indicate the device’s power status and operational phases.
In summary, the NI-9157 CompactRIO Chassis combines flexibility, performance, and reliability, making it an ideal choice for engineers and professionals working on sophisticated control and monitoring systems.
