For supply of intrinsically safe 2-wire transmitters and SMART transmitters |
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 |
รายละเอียด |
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. |
