Product specs for National Instruments Corporation 779009-01

The NI 9151 expansion chassis connects directly to the digital connector on most NI R Series PXI, PCI, and PCI Express multifunction reconfigurable I/O (RIO) devices and houses up to four NI C Series I/O modules for high-performance, industrial signal conditioning. You can choose from a variety of I/O modules including 24 V industrial digital I/O with up to 32 channels per module, which is ideal for creating industrial counter/timers, electromechanical relays, 80 mV thermocouple inputs, 5 V IEPE accelerometer analog inputs, and simultaneous voltage and current analog outputs. Visit ni.com/compactrio for the latest information on module availability.

View the following list to determine how many R Series expansion chassis you can connect to your R Series device based on the number of digital connectors for each device.
