AD-STV 40 GVC

Description

The supply isolation amplifier AD-STV 40 GVC is designed for the galvanic isolation and amplification of transmitter signals (0/4-20 mA) and standard analog signals (0/4-20 mA and 0/2-10VDC). When connecting a 2 - wire transmitter, it is powered directly through an electrically isolated and current limited power supply voltage. The standard signals 0/4-20 mA and 0/2-10 V are freely selectable via switch or terminal on both the input and at the output. All ranges are calibrated fixed, but can be adjusted via front-trimmer. In addition, this device comes standard with a configuration interface AD-PC, with which the input and output measurement signal with the optional AD-Studio programming software in the range of max. 20 mA or 10 VDC can be freely programmed. The selected linear output signal follows the input size up to a limit independent of the connected load. Input, output and power supply voltage are galvanically isolated from each other with high insulation. An integral electronic wide range power supply with high efficiency prevents strong heating and allows high output loads.
