The isolation amplifier AD-TV 1 GX, with a construction width of only 6.2 mm, serves the galvanic separation of DC voltage signals. The output signal follows linear the input variable and is, up to a limiting value, independent of the connected burden (0-10 VDC, 1:1 input/output). Due to the narrow design, a high packing density is achieved. In combination with a DIN rail connector, the wiring is considerably reduced.

The isolation amplifier AD-TV 2 GX, with a construction width of only 6.2 mm, serves the galvanic separation of DC current signals. The output signal follows linear the input variable and is, up to a limiting value, independent of the connected burden (0/4-20 mA, 1:1 input/output). Due to the narrow design, a high packing density is achieved. In combination with a DIN rail connector, the wiring is considerably reduced.

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.

The isolation amplifier AD-STV 2 GX with integrated transmitter supply, with its construction width of only 6.2 mm, serves the galvanic separation and amplification of transmitter signals (4-20 mA). The 2- or 3-wire transmitter is supplied directly through a galvanic separated supply voltage. The input signal can be selected via a DIP switch. For range change, a manual adjustment is required, the initial values and final values can be adjusted via a trimmer. Input voltage, output voltage and supply voltage are galvanic separated from each other. Due to the narrow design, a high packing density is achieved. In combination with a DIN rail connector, the wiring is considerably reduced.

The supply separation amplifier AD-STV 24 GVB serves the galvanic separation and amplification of transmitter signals (0/4 20 mA). The 2- or 3-wire transmitter is supplied direct through a galvanically separated and current limited supply voltage. The output signal follows the input magnitude linear and is independent of the connected burden uptoa limiting value. Input, output and the supply voltage are separated galvanically from each other with high insulation. An integral, electronic power pack is designed with a voltage range of 11 to 30 VDC, also for 12V battery voltage. With the combination of connection terminals, which can be pulled off, and a construction width of 13 mm, a high packing density and high working ergonomics are achieved.

The supply isolation amplifier AD-STV 24 GL serves the galvanic isolation and amplification of current signals in the range 0/4...20 mA. The transmitter is supplied by an isolated and limited supply voltage. Input, output and power supply are galvanically isolated. The electronic wide range power supply avoids an excessive heating. In combination with the small shape, high packing densities can be achieved.

The AC buffer amplifier AD-TV 581 GS serves the detection of effective values of sinusoidal alternating currents. The input variable 0-1A AC or 0-5A AC is here freely selectable via terminal.The alternating current is galvanic separated via a current transformer 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 an optional interface.

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.

With the current converter AD-SW 3 GL up to three independent current magnitudes can be converted to a DC voltage of ±0-10 V. The amplitude value (sinus) or the true effective value (True RMS) can be presented. Inputs, outputs and supply voltage are galvanically separated from each other with high insulation. The outputs refer to a common mass. An integral electronic wide range power pack with high efficiency prevents strong increase in heat.

The separation converter serves the galvanic separation of impressed currents. It obtains its auxiliary energy form the input signal. The connection of an additional auxiliary voltage is not necessary. The output current is independent of the connected load up to the maximum value.
