AD-STV 2 GX

Description

The supply isolation amplifier AD-STV 2 GX with its width of only 6.2 mm is used for galvanic isolation and amplification of transmitter signals (4-20 mA). The 2- or 3-wire transmitter is supplied directly by a galvanically isolated supply voltage. The input signal can be selected via DIP switches. Manual readjustment is required when switching the measuring range, the start and end values can be set using trimmers. Input, output and the supply voltage are galvanically separated from each other. A high packing density is achieved thanks to the narrow design. In combination with DIN rail connectors, the wiring effort is reduced considerably.

AD-STV 2 GX

Application

Supply and data acquisition of 2- or 3-wire transmitters such as pressure transmitters, temperature transmitters, etc. with simultaneous amplification and galvanic isolation. Can also be used as a pure burden amplifier.

Specific characteristics

  • narrow 6.2mm construction
  • Current and voltage input (switchable)
  • easy configuration using DIP switches on the side of the device
  • Supply via DIN rail connector
