DEHNpipe CD Ex (i) + Ex (d) Surge arrester SPDs for Use in Potentially Explosive Atmospheres • Surge protective device for field devices with spare cable gland or fieldbus distributors in potentially explosive atmospheres • Flexible use in Ex(i) and Ex(d) circuits • Protection of two signal circuits in a single device • Easy installation and retrofitting • ATEX, IECEx and FISCO approval Different DEHNpipe versions for two signal circuits or one supply circuit and one signal circuit for field devices in potentially explosive atmospheres The devices of the DEHNpipe family are made of corrosion-resistant stainless steel and can be directly screwed onto a field device in a potentially explosive atmosphere. Like a field cable, the permanently connected lines are connected to the terminals of the field device. The surge arresters can be used for a wide range of applications. A single arrester is capable of protecting two unearthed signal circuits or the supply circuit of the field device and one signal circuit. When installed in a fieldbus distributor, two field devices can be protected by a single arrester. The surge arresters are designed in such a way that the protection components are arranged in parallel to the cable run. Due to the different approvals, the surge arresters can be installed on field devices in intrinsically safe measuring circuits Ex(i) or on devices with flameproof enclosure and are suitable for use in Ex zone 1 or 2. The surge arresters are ideally suited for installation in process environments, for example on transducers or field bus devices. 4-20 mA measuring circuits or bus systems up to 30 V are typical fields of application.
