National Instruments NI-9151 CompactRIO Chassis
The NI-9151 (Part Number: 779008-01) is a CompactRIO Chassis from National Instruments capable of linking straight to the digital connectors on R Series Devices such as Multifunction Reconfigurable I/O Devices or PXI Reconfigurable I/O Modules. In addition, this device accommodates C Series I/O Modules for high-performance, industrial signal conditioning applications. This Chassis can be mounted on a 35 mm DIN rail or on a panel—the DIN rail mounting option is ideal if the user has a DIN rail configuration or if they require the capability to swiftly take the CompactRIO Chassis out of the configuration. For the DIN rail mount option, a clip is required as well. On the other hand, the panel mount option is suitable for applications involving high shock and vibration. Also, keep in mind that prior to mounting the NI-9151, the user should ensure that the cable is not attached to the Chassis.
The National Instruments NI-9151 CompactRIO Chassis must have the green panhead screw at the end connected to ground. If the user is utilizing shielded cables for the I/O module wiring, then they can link the shield to the panhead screw. To link the Chassis to an R Series Device, the user must utilize a SHC68-68-RDIO cable. To use C Series modules with the NI-9151, the user should install NI CompactRIO Module Support software on their system, as well as the NI R Series Multifunction RIO Device Drivers software. Additionally, this model is easily equipped with a single 68-pin connector.
Other features to keep in mind about this CompactRIO Chassis are that the NI-9151 does not support sleep mode and has an active mode chassis power consumption of 0.5 W. Additionally, it is capable of adding a 4-slot expansion chassis to one R Series device, and it can generate any timing, triggering, and synchronization scheme with a resolution of 25 ns. It consumes a maximum power of 0.5 W when in active mode. The NI device weighs 18.6 oz, and measures 5.6 x 3.5 x 2.3 in. in physical dimensions. It has a recommended operating temperature range of -40 °C to 70 °C.

National Instruments NI-9151 Frequently Asked Questions
Question: Does the NI-9151 support sharing timebases between modules that have Delta-Sigma ADC?
Answer: No, the cRIO Chassis does not support sharing timebases between modules that have Delta-Sigma ADC.
Question: Which devices can the NI-9151 connect to?
Answer: The chassis can connect to any digital connector of the PXI/PCI/PCIe-781x, 783xR, 784x, and 785xR R Series devices.
Question: Which accessories can be used with the CompactRIO Chassis?
Answer: The NI-9151 can be used with the SHC68-68 RDIO Shielded cable and the NI-9977 C Series Filler Module for Empty Slot.
Question: When I connect my R Series card to the NI-9151, my computer does not recognize the modules in the Chassis. What is the cause of this problem?
Answer: A potential cause could be a tripped fuse. This can be checked by plugging the R Series card into a breakout board (ex: the SCB-68) and measuring the voltage between the +5V and ground pin. If the voltage is +5V, then the fuse is fine. However, if the voltage is 0, then the fuse has been tripped and needs to be replaced.
