AC Isolation Amplifier
AD-TV 591 GS

back to products


The alternating voltage isolation amplifier AD-TV 591 GS detects the true RMS value of an alternating voltage. The input variable 0-250V AC or 0-450V AC is here freely selectable via terminal. The alternating voltage is galvanic separated and transformed into an impressed DC standard signal 0/4-20 mA or 0/2-10 VDC. The zero point and the range of the measuring signal can be adjusted with trimmers at the front. The trimmers can be activated via a wire bridge. The start of the output range can be modified via a wire bridge from 0 to 4mA or from 0 to 2V, exceeding the measuring range or falling below the measuring range is indicated with a flashing LED at the front of the device. The device can be configured with a PC software via the interface on the front interface.


Freely configurable transformation of AC voltage signals to DC standard signals, with simultaneous galvanic separation.
