Description

A20100 Repeater Power Supply | Input 4 … 20 mA | Isolation up to 600 V

Repeater power supply in a 6 mm housing with calibrated switching of output signals, HART transmission and protective separation.

  • Extremely flat
    3-port isolation in a 6 mm modular housing
  • Flexible and extremely precise
    Calibrated switching of output signals
  • Quick and easy configuration
    using lateral DIP switches – easy to access, yet protected against accidental adjustment
  • Low-cost assembly
    Supply of the current loop and galvanic isolation of the measurement signal in one device
  • Protective separation
    up to 300 V according to EN 61140
  • SMART transmitter
    (acc. to HART specification)
  • Cross-connection combs for power supply
    Power supply only wired once for almost any number of parallel repeater power supplies
  • 5-year warranty

Repeater power supply for 2-wire transmitters (current loop powered sensors) in an extremely compact 6-mm housing. The A20100 supplies the transmitter with power and transmits the measurement signal to the output with galvanic isolation and high accuracy.

In case a signal other than the 4 to 20 mA current loop signal is required, the repeater power supply provides various output signals which can be selected via DIP switches. Of course HART signals are transmitted unaltered. The width of just 6 mm also allows use of the repeater power supply in the tightest of spaces.
