PC-based Data Acquisition Unit
High Withstand Voltage (Reinforced Insulation)
Reinforced (double) insulation has been provided between the input terminals and the case to achieve a high withstand voltage of 600 Vrms/VDC (continuous). As shown below, each battery voltage can be measured even if the batteries are stacked to increase common-mode voltages.
Noise Rejection (MX110-UNV-H04)
MX input modules employ integrating A/D converters with superior noise rejection performance. In particular, the MX110-UNV-H04 Four-Channel High-Speed Universal Input Module incorporates an integrating A/D converter for each input channel, thereby exhibiting strong noise rejection performance in high-speed measurement. Moreover, the digital filtering function is effective on noises that cannot be fully rejected even with integrating A/D converters. Time constants can be selected from 5 to 100 measurement interval times. Therefore, filtering can be applied according to the noise to be rejected.
Example of Noise Rejection
When the noise source in the left figure was applied to the MX, the result in the right figure was obtained. High-speed measurement can be stably performed even in noisy environments.
|Noise source applied to the MX
A noise signal was applied between H and L (in normal mode).
