The ICP DAS PET-7217RMS Power over Ethernet module has 8-channel differential AC input and 4-channel digital outputs which 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 PET-7217RMS is a complete, high-accuracy, RMS-to-DC converter that computes the True RMS DC value of any complex waveform. The ICP DAS PET-7217RMS module also features 4 kV ESD protection, 2500 VDC intra-module isolation, and ±35 Vrms/±28 VDC overvoltage protection.

This Ethernet I/O module can be remotely controlled using the Modbus TCP/UDP protocol via an Ethernet network which makes it ideal for integration with HMI, SCADA, PLC and other industrial control software systems.
