SKU: WG25

WG25 Repeater Power Supply | Input 4 … 20 mA | Ex | Transmission of HART signals

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

Affordable
Good price due to omission of integrated power supply
No mains supply required
Cost savings due to lower wiring effort, no mains influences
Low power losses
No unnecessary heating in the enclosure
Protective separation
according to EN 61140 Protection of maintenance staff and downstream devices against excessively high voltages
HART transmission
Bidirectional 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, therefore the related costs are not incurred

The Task
The passive WG25 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.

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

The Technology
Using Knick TransShield technology, the WG25 has specifications that were previously not available in passive repeater power supplies:

Extremely high reliability, MTTF of over 300 years
Protective separation, transient protection
10 kV test voltage (optional)
High electromagnetic compatibility
Extremely low residual ripple and common-mode interference
Outstanding pulse formation
HART transmission
Hazardous/safe area separation
