The following inputs can be used on MXLOGGER or the MX100/DARWIN API (sold
separately). These inputs cannot be used with the MX100 Standard Software.

Measurement Interval, Integration Time, and Filter
The table below shows the available measurement intervals. The module is equipped
with an integrating A/D converter. The selectable integration time varies depending on
the measurement interval as shown in the table below. For details about the relationship
between noise and integration time, see section 2.7, “Measures against Noise on the
MX100” In addition, the type of noise rejection filter switches as shown in the table below.

*1 If the measurement interval is 100 ms, burnout detection is carried out on a single channel during
one measurement interval. Therefore, when starting measurement during the burnout condition or
thereafter, burnout can be detected for up to 10 measurements (approximately 1 second).
*2 Since the power supply frequency noise is not rejected, the measured vales may fluctuate especially
with temperature measurement. In such cases, set the measurement interval to 500 ms or higher, or
use the 4-CH, High-Speed Universal Input Module.
Measurement Synchronization
The module is equipped with a single A/D converter, and measurement is made
sequentially. Therefore, measurements of each channel are not synchronized.
Common Mode Voltage
The common mode voltage between channels in a single module is 120 VACrms when
the signal is applied continuously. The common mode voltage between modules and
between a module and earth is 600 VACrms when the signal is applied continuously.
