AD-TV 3 GX

Description

The VARIO isolation amplifier AD-TV 3 GX, with a construction width of only 6.2 mm, serves the galvanic separation, conversion and amplification of DC current signals and voltage signals (0/4-20 mA and 0/2-10 V). The signal magnitudes can be selected with DIP switches. For range changing, manual adjustment is required, the initial values and final values can be adjusted via a trimmer. The output signal follows linear the input variable and is, up to a limiting value, independent of the connected burden. Due to the narrow design, a high packing density is achieved. In combination with a DIN rail connector for bridging the supply voltage, the wiring is considerably reduced.
