Connector Types

The NI-9209 has more than one connector type: NI-9209 with spring terminal and NI-9209 with DSUB. Unless the connector type is specified, NI-9209 refers to all connector types.

The NI-9209 with spring terminal is available in two types: push-in spring terminal and spring terminal. The push-in type spring terminal connector is black and orange. The spring terminal connector is black. NI-9209 with spring terminal refers to both types unless the two types are specified. Differences between the two types of spring terminal connectors are noted by the connector color.

Definitions

NI-9209 with Spring Terminal Safety Voltages

Connect only voltages that are within the following limits:

Isolation

Channel-to-channel

None

Channel-to-earth ground

Continuous

250 V RMS, Measurement Category II

Withstand up to 5,000 m

3,000 V RMS, verified by a 5 s dielectric withstand test

Measurement Category II

Caution Do not connect the NI-9209 with spring terminal to signals or use for measurements within Measurement Categories III or IV.
Attention Ne pas connecter le NI-9209 with spring terminal à des signaux dans les catégories de mesure III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.

Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.

NI-9209 with DSUB Safety Voltages

Connect only voltages that are within the following limits:

Isolation

Channel-to-channel

None

Channel-to-earth ground

Continuous

60 V DC, Measurement Category I

Withstand

1,000 V RMS up to 3,000 m, verified by a 5 s dielectric withstand test; 860 V RMS up to 5,000 m

Measurement Category I

Caution Do not connect the NI-9209 with DSUB to signals or use for measurements within Measurement Categories II, III, or IV.
Attention Ne pas connecter le NI-9209 with DSUB à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.
Warning Do not connect the NI-9209 with DSUB 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 NI-9209 with DSUB 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 NI-9209 with DSUB 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 NI-9209 with DSUB 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 NI-9209 with DSUBne 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 NI-9209 with DSUB 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.

Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
