Introduction

The I-87017W-RMS is an 8-channel differential AC input module that is used to convert the AC input signals to their true RMS DC values. The RMS input range can be from +150 mVrms to +10 Vrms, and each channel can be configured individually. The I-87017W-RMS is a complete, high-accuracy, RMS-to-DC converter that computes the true RMS DC value of any complex waveform. It also features 4 kV ESD protection, 3000 VDC intra-module isolation and +/-35 VDC overvoltage protection.
