• Installation into the cable run ensures maxi-mum degree of protection
• Surges are discharged via the enclosure of thefield device
• For almost all types of two-wire field deviceswith suitable cable gland
Surge arrester for outdoor use to be screwed onto two-wire field devices.Stainless steel, installation with cable gland up to IP 67.
DEHNpipe
Surge arrester
DEHNpipe is made of corrosion-resistant stainless steel and is screwedonto the field device instead of a conventional cable gland. The perma-nently connected lines are then connected to the terminals of the fielddevice. Thus the protective components are directly situated in the cablerun, allowing energy-coordinated surge protection. The arrester protects
the inside of the field device against dangerous overvoltage with theinterfering impulses being discharged via the metal enclosure only andnot via the inside of the field device. Earthing accessories are also avail-able for plastic field enclosures.
DEHNpipe is designed for two-wire measuring sensors with 4-20 mA interfaces. The surgearresters ensure energy-coordi-nated surge protection for fielddevices in outdoor areas, min-imising space requirements andreducing installation work.
DPI types
The universal surgearrester can also be usedfor applications allowingonly single assignmentof the field device termi-nals or providing spacefor only one cable gland.
Installation benefits
Due to the two-part design of the arrester, the field cable can be connect-ed as usual, just as being connected to a measuring sensor.Thanks to the cable gland, a degree of protection IP 67 is achieved.DEHNpipe allows to implement conventional earthing concepts for cableshields of field cables. Depending on the cable gland used, the cableshield is either earthed directly or indirectly or is not earthed at all.Indirect earthing integrates the shield into the protection concept – with-out leakage pickups.

DEHNpipe CD Ex (i) + Ex (d)
Surge arrester
The devices of the DEHNpipe family are made of corrosion-resistantstainless steel and can be directly screwed onto a field device in a poten-tially explosive atmosphere. Like a field cable, the permanently connect-ed lines are connected to the terminals of the field device. The surgearresters can be used for a wide range of applications. A single arresteris capable of protecting two unearthed signal circuits or the supply circuitof the field device and one signal circuit. When installed in a fieldbus dis-tributor, two field devices can be protected by a single arrester. The surgearresters are designed in such a way that the protection components arearranged in parallel to the cable run.
Due to the different approvals, the surge arresters can be installed onfield devices in intrinsically safe measuring circuits Ex(i) or on deviceswith flameproof enclosure and are suitable for use in Ex zone 1 or 2.
The surge arresters are ideally suited for installation in process environ-ments, for example on transducers or field bus devices. 4-20 mA measur-ing circuits or bus systems up to 30 V are typical fields of application.
