Safety Interlock

The safety interlock feature is designed to prevent users from coming in contact with hazardous voltage generated by the SMU in systems that implement protective barriers with controlled user access points.

Caution Hazardous voltages of up to the maximum voltage of the PXIe-4136 may appear at the output terminals if the safety interlock terminal is closed. Open the safety interlock terminal when the output connections are accessible. With the safety interlock terminal open, the output voltage level/limit is limited to ±40 V DC, and protection will be triggered if the voltage measured between the device HI and LO terminals exceeds ±(42 V peak ±0.4 V).
Attention Des tensions dangereuses allant jusqu'à la tension maximale du PXIe-4136 peuvent apparaître aux terminaux de sortie si le terminal de verrouillage de sécurité est fermé. Ouvrez le terminal de verrouillage de sécurité lorsque les connexions de sortie sont accessibles. Lorsque le terminal de verrouillage de sécurité est ouvert, le niveau ou la limite de tension de sortie est limité à ± 40 V CC, et la protection se déclenchera si la tension mesurée entre les terminaux HI et LO de l'appareil dépasse ± (42 Vpic ± 0,4 V).
Caution Do not apply voltage to the safety interlock connector inputs. The interlock connector is designed to accept passive, normally open contact closure connections only.
Attention N'appliquez pas de tension aux entrées du connecteur de verrouillage de sécurité. Le connecteur de verrouillage est conçu pour accepter uniquement des connexions à fermeture de contact passives, normalement ouvertes.

Examples of Calculating Accuracy Specifications

Specifications listed in examples are for demonstration purposes only and do not necessarily reflect specifications for this device.

Tcal is the internal device temperature recorded by the PXIe-4136 at the completion of the last self-calibration.

Example 1: Calculating 5 °C Accuracy

Calculate the accuracy of 900 nA output in the 1 µA range under the following conditions:

Ambient temperature 28 °C
Internal device temperature within Tcal ±5 °C
Self-calibration within the last 24 hours

Because the device internal temperature is within Tcal ±5 °C and the ambient temperature is within 23 °C ±5 °C, the appropriate accuracy specification is the following value:

0.03% + 200 pA

Calculate the accuracy using the following formula:

Accuracy ⁢   =   900 ⁢ ⁢   nA ⁢ *   0.03 %   +   200 ⁢ pA
=   270 ⁢   pA ⁢ +   200 ⁢   pA
=   470 ⁢ pA

Therefore, the actual output is within 470 pA of 900 nA.

Example 2: Calculating Remote Sense Accuracy

Calculate the remote sense accuracy of 500 mV output in the 600 mV range. Assume the same conditions as in Example 1, with the following differences:

HI path lead drop 3 V
HI sense lead resistance 2 Ω
LO path lead drop 2.5 V
LO sense lead resistance 1.5 Ω

Because the device internal temperature is within Tcal ±5 °C and the ambient temperature is within 23 °C ±5 °C, the appropriate accuracy specification is the following value:

0.02% + 100 μV

Because the device is using remote sense, use the following remote sense accuracy specification:

Add 3 ppm of voltage range plus 11 μV per volt of HI lead drop plus 1 μV per volt of lead drop per Ω of corresponding sense lead resistance to voltage accuracy specifications.

Calculate the remote sense accuracy using the following formula:

Accuracy ⁢   =   ( 500 ⁢   m V ⁢   *   0.02 %   +   100 ⁢   μV ) ⁢ +   600 ⁢ ⁢   ⁢   mV ⁢   *     3 ⁢   ppm ⁢   + 11 ⁢   μV 1 ⁢   V ⁢ of ⁢ ⁢   lead ⁢     drop ⁢ *   3 ⁢   V ⁢ +   1 ⁢     μ V V ⁢ *   Ω ⁢ ⁢ ⁢ *   3 ⁢   V ⁢   *   2 ⁢     Ω ⁢ +   1 ⁢     μ V V ⁢ *   Ω ⁢     *   2.5 ⁢     V ⁢   *   1.5 ⁢   ⁢ Ω
=   100 ⁢   μV ⁢ +   100 ⁢   μV ⁢ +   12.8 ⁢   μV ⁢ ⁢   *     3 ⁢ ⁢ ⁢ +   6 ⁢   μV ⁢ +   3.8 ⁢   ⁢ μV
=   248.2 ⁢   ⁢ μV

Therefore, the actual output is within 248.2 µV of 500 mV.

Example 3: Calculating Accuracy with Temperature Coefficient

Calculate the accuracy of 900 nA output in the 1 µA range. Assume the same conditions as in Example 1, with the following differences:

Ambient temperature 15 °C

Because the device internal temperature is within Tcal ±5 °C, the appropriate accuracy specification is the following value:

0.03% + 200 pA

Because the ambient temperature falls outside of 23 °C ±5 °C, use the following temperature coefficient per °C outside the 23 °C ±5 °C range:

0.0006% + 4 pA

Calculate the accuracy using the following formula:

Temperature ⁢ ⁢ Variation   =   ( 23 ⁢   ° C ⁢ −   5 ⁢ ⁢     ° C )   − 15 ⁢ ° C ⁢ =   3 ⁢   ° C  
Accuracy ⁢   =   ( 900 ⁢ ⁢     nA ⁢   *   0.03 %   +   200 ⁢   ⁢ ⁢ pA ) +   900 ⁢   ⁢ ⁢   nA ⁢ *   0.0006 % ⁢   + 4 ⁢   ⁢ p A 1 ⁢   ° C   ⁢ *   3 ⁢ ⁢     ° C
=   350 ⁢   pA ⁢ +   28.2 ⁢   pA
=   498.2 ⁢   ⁢   pA

Therefore, the actual output is within 498.2 pA of 900 nA.
