Description
NI-9853 sbRIO-9853 CompactRIO and NI-RIO modules
Warning
Do not connect the product to signals or use for measurements within Measurement Categories II, III, or IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category II, III, or IV which may have transient overvoltages above what the product can withstand. The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements.
Mise en garde
Ne pas connecter le produit à des signaux dans les catégories de mesure II, III ou IV et ne pas l’utiliser pour des mesures dans ces catégories, ou des mesures sur secteur ou sur des circuits dérivés de surtensions de catégorie II, III ou IV pouvant présenter des surtensions transitoires supérieures à ce que le produit peut supporter. Le produit ne doit pas être raccordé à des circuits ayant une tension maximale supérieure à la tension de fonctionnement continu, par rapport à la terre ou à d’autres voies, sous peine d’endommager et de compromettre l’isolation. Le produit peut tomber en panne et son isolation risque d’être endommagée si les tensions transitoires dépassent la surtension transitoire nominale. Une analyse des tensions de fonctionnement, des impédances de boucle, des surtensions temporaires et des surtensions transitoires dans le système doit être effectuée avant de procéder à des mesures.

Backshell Kit
For signal wire strain relief, high-vibration environments, or protection from high voltages, use the NI 9940 backshell kit. Note that this kit is not compatible with the D-Sub version of the module.
D-Sub Accessories
The D-Sub version of the NI 9264 module was designed to accommodate standard 37-pin D-Sub components. NI offers a variety of cables and terminal blocks for this connector option. To eliminate the need for a breakout panel and conserve space, use the NI 9933 37-pin D-Sub connector block. This accessory kit comes with a D-Sub to screw-terminal converter as well as a protective shell to create a custom cable for your specific application.
