Bộ chuyển đổi 3 kênh đầu vào đo dòng 20A sang tương tự ICP DAS DN-843I-CT-20 CR
Feature
• AC/DC Source Input
• Linear Attenuation Ratio
• High Current Input Measurement
• Isolation Input
• Easily Wire Connection
Introduction
The maximum input range is from ±1 A to +/- 50 A and can be attenuated to from ±1.6 V to ±10 V. The "I" version provide 3000 VDC intra-modules isolation and 3000 VDC channel to channel isolation to avoid the noise interference from inputs to outputs or channel to channel. It can be used with the analog input modules such as I-7017 and I-87017 etc. to measure the high current.
