Another groov I/O module was just released as the groov EPIC system continues to expand.

We've just added GRV-IVIRMS-10 to our growing list of I/O options for
groov EPIC.

As the latest addition to the family of analog voltage input modules, GRV-IVIRMS-10 provides true RMS (root mean square) voltage monitoring for 10 inputs up to 300 VAC/VDC with channel-to-channel isolation and 20-bit resolution. True RMS calculation is critical for non-sinusoidal power monitoring applications such as variable speed drives (VSD), heating controls, computers, HVAC, and solid-state components where typical peak measurement averaging can under- or over-shoot actual voltage by 5 - 40%.
