MN32S
Item article:
The МН32S mezzanine is designed for measuring instantaneous voltage values across thirty-two differential channels.
The mezzanine takes measurements in the following modes:
-
“Once” - a single measurement of the sequence of channels specified by the user is performed;
-
“Block” - measurements are performed until a predetermined number of samples (results) of channel sequences specified by the user are received;
-
“Continuous” - measurements are performed according to a user-defined sequence in a continuous cycle until a stop command is received.
All input lines of the mezzanine can, at the command of the user, be disconnected from the control object.
| Number of measuring channels 32 |
Measurement ranges of instantaneous voltage values:
|
| Maximum allowable voltage at mezzanine inputs 35 V | |
| Input impedance of the measuring channel 2 MOhm | |
Limits of permissible basic relative measurement error of instantaneous voltage values at the minimum sampling period and at ambient temperature + (20 ± 2) °С,%:
|
The limits of the permissible additional relative error in the measurement of voltage values at the minimum sampling period for all measurement ranges should be,% ± 0.002 T, where T is the deviation of the ambient temperature from 18 ºС (for the temperature range from 5 to 18 ºС) or from 22 ºС (for the temperature range from 22 to 40 ºС). |
| The sampling period is set the same for all channels participating in the measurement, in the range from 302 μs to 16.777214 with a step of 1 μs | |
| The mezzanine measuring chains are galvanically isolated from the housing. Galvanic isolation voltage of at least 200 V. Resistance of galvanic isolation of at least 20 MOhm |
