Repeater Power Supply

IsoAmp PWR A 20100

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

Repeater power supply for 2-wire transmitters (current loop powered sensors) in an extremely compact 6-mm housing. The A 20100 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.

Facts

  • Extremely flat: 3-port isolation in a 6-mm modular housing
  • Flexible and extremely accurate: calibrated switching of the output signals
  • Quick and easy configuration: configuration using lateral DIP switches, for easy access, yet protected against accidental adjustment
  • Cost-effective design: 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 (according to HART specification)
  • Cross-connections for power supply - power supply only wired once for any number of parallel repeater power supplies
  • 5-year warranty 

The Task
Flexible and safe supply of 2-wire transmitters via the 4 ... 20-mA current loops with simultaneous transmission of data protocols for SMART transmit-ters / HART communication.  Conversion of the output signal into 0 … 20 mA or 0 … 10 V, if necessary.

The Problems
Good isolator properties combined with high transmission accuracy often result in complex systems that cost space and money.
Galvanic isolation of the supply
and signal processing, however, are frequently indispensable in order to exclude measuring problems right from the start. Thus the range of pos-sible alternatives within the budget is often limited.

The Solution
Knick is the first manufacturer to provide a repeater power supply for 2-wire transmitters in an extremely compact 6-mm housing - the IsoAmp PWR A 20100. It supplies the transmit-ter with power and transmits the mea-surement 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 transmit-ted unaltered. The width of just 6 mm also allows for the use of the repeater power supply in the tightest of spaces.
