Note The module will typically provide up to the all channels (trip) current before the limit activates. Once the limit activates, the typical total available current will drop to the all channels (hold) current to limit internal power dissipation. The module will not recover from the limit until the static current drawn drops below this typical hold current. NI recommends that you lower the static current required to drive the loads on all channels to a level below the all channels (hold) current if you expect to activate the limit.

Power on state[1]1 When the module powers on, a glitch occurs for 500 µs peaking at -3 V.

0 V

Power off state[2]2 The power-down voltage peaks at -3 V then discharges to 200 mV in 100 ms. You can add a load to reduce peak voltage.

FPGA user-controlled I/O sampling[4]4 FPGA user-controlled I/O sampling provides low-level access to write data and update sample timing. This allows for faster update rates than the minimum update time by overlapping or pipelining writes and updates.

Measurement Category I

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.

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.

1 When the module powers on, a glitch occurs for 500 µs peaking at -3 V.

2 The power-down voltage peaks at -3 V then discharges to 200 mV in 100 ms. You can add a load to reduce peak voltage.

3 The minimum amount of time between the start of a write and the update of the DAC output when using NI-DAQmx or CompactRIO FPGA user-controlled I/O sampling.

4 FPGA user-controlled I/O sampling provides low-level access to write data and update sample timing. This allows for faster update rates than the minimum update time by overlapping or pipelining writes and updates.

6 Uncalibrated accuracy refers to the accuracy achieved when acquiring in raw or unscaled modes where the calibration constants stored in the module are not applied to the data.
