Introduction
The DNM-843VI series and DNM-848VI series are voltage input attenuator. The maximum input range is from ±10 Vpp to ±800 Vpp can be attenuated to ±10 Vpp. 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, I-87017, M-7017RMS and I-87017W-RMS etc. to measure the high voltage.
