    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.

    spd-note-caution
    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 Vpk ±0.4 V).

    spd-note-caution
    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.

    Examples of Calculating Accuracy Specifications[16]

    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[17]
    Self-calibration within the last 24 hours

    Solution

    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

    Solution

    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 + 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 mV * 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

    Solution

    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 = ( 500 nA * 0.03 % + 200 pA ) + 900 nA * 0.0006 % + 4 p A 1 ° C * 3 ° C

       = 350 pA + 28.2 pA

    = 378.2 pA

    Therefore, the actual output is within 378.2 pA of 900 nA.
