The M-7017RMS a high-accuracy, RMS-to-DC converter which can compute AC input signals into the true RMS DC value of any complex waveform. It has 8-channels differential inputs which can be configured individually. RMS input range scales from +150 Vrms to +10 Vrms for this device and it features 4 kV ESD protection and 2500 VDC intra-module isolation and +/-35 VDC overvoltage protection.
