Introduction
The ET-7217RMS is an 8-channel differential AC input and 4-channel digital outputs 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 ET-7217RMS 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, 2500 VDC intra-module isolation, and ±35 Vrms/±28 VDC overvoltage protection.
