About us
At a Glance
The TSX AEY 414 module proposes 23 ranges for each of its inputs, which can be configured channel by channel.
Precision
Precision for each input is shown by the formula:
Equation parameters:
Parameter
Meaning
C
Constant for the range in question
K
Coefficient of proportionality
M
Absolute value of the measurement
A measurement error is therefore made up of a constant value C and a value proportional to the measurement K, which can be different depending on measurement polarity.
For thermocouple ranges, measurement error also takes into account cold junction compensation and linearization errors, and for current ranges, external resistance error (shunt).
Diaphony
Diaphony is expressed in dB and is shown in the formula:
Equation parameters:
Parameter
Meaning
V M
Full scale voltage in the least sensitive range
V m
Voltage error on the following channel, configured in the most sensitive range (due to the presence of VM)
In the example, VM equals +10 V and Vm is the error due to the presence of +10 V on the following channel configured in +/- 20 mV.
Common Mode Rejection
Common mode rejection between channel and ground is expressed in dB and is shown in the formula:
Equation parameters:
Parameter
Meaning
V MC
Common mode voltage expressed in VDC or VAC (50 / 60 Hz)
V em
Voltage error on the measurement (reduced by the conversion resolution) expressed in VDC
For a current range, common mode rejection can naturally be deduced from this formula.
For thermoprobe or thermocouple ranges, common mode rejection is not applicable.
Series Mode Rejection at 50 / 60 Hz
Series mode rejection at 50 / 60 Hz is expressed in dB and is shown in the formula:
Equation parameters:
Parameter
Meaning
V MS
Series mode voltage expressed in peak to peak volts
V em
Voltage error on the measurement (reduced by the conversion resolution) expressed in VDC
For a current range, series mode rejection can naturally be deduced from this formula.
For thermoprobe or thermocouple ranges, series mode rejection is not applicable.
