WG 25

Fontes Alimentadas por Loop

The passive WG 25 repeater power supply is loop-powered. It is used for galvanic hazardous-area separation of a 2-wire supply line and transmits both 4 … 20 mA and HART® signals in both directions. With a voltage drop of just 4.2 V, the WG 25 uses the supply optimally so that all common 2-wire transmitters can be connected.

Compared with active repeater power supplies, it has considerable price and reliability advantages. Multi-channel systems require only one central, safe-area power supply that does not even need protective separation.

Facts

  • Low-cost due to omission of the integrated power supply
  • No mains power required costs savings doe to lower wiring effort
  • No mains interference
  • Low power loss no unnecessary heating in the enclosure
  • Protective separation according to EN 61140: protection of the maintenance staff
    and subsequent devices against excessively high voltages
  • HART® transmission: bi-directional point-to-point transmission of digital data
    according to the HART® specification
  • EMC tested RFI suppressed and surge proof: reliable operation even
    with electromagnetic interference
  • Maximum reliability: no maintenance work so the associated costs are not incurred

5 year warranty
