Explosion-proof Call Station DWEx-IP2 is a subscriber equipment designed for use in decentralized and centralized intercom and PA/GA systems IPN and ArmtelICS at industrial and transportation enterprises.
DWEx-IP2 is a pure IP Flameproof Field Call Station at the market that connect to IP network without any additional gateways.
DWEx-IP2 Flameproof IP Field Call Station is designed for operation in explosion hazardous dusty and gaseous environments excluding mines and their superstructures with hazards related to mine gas according to explosion protection marking «1Ex d e ib IIC T4 Gb» and «Ex tb IIIC T 135°C Db» [GOST 31610.0-2014 (IEC 60079-0:2011), PUE] and «II 2 G Ex db eb Ib IIC T4 Gb» and «II 2 D Ex tb IIIC T135°C Db IP66» (EN 60079-0:2012).
DWEx-IP2 has explosion-proof categories «explosion-proof equipment»», provides protection type of «flameproof enclosure (d)», provides protection «increased safety (е)», provides protection «intrinsically-safe circuit «i» type «ib» and provides protection type of «dust ignition protection type «tD».
DWEx-IP2 contains embedded software and configuration data stored in RОM, which allows it to communicate with other digital communication system users directly, handle priority connections and manage communication and indication modes. An IP-network built using standard network equipment is used to facilitate communication.
DWEx-IP2 is designed for employment in an explosion proof zones of the premises and external installations in accordance with certain explosion proof marking, requirements Technical Regulation of the Customs Union “On safety of equipment intended for use in explosive atmospheres” (TR CU 012/2011), GOST IEC 60079-14-2013, chapter 7.3 «Regulations for Electrical Installation» (PUE), ATEX 2014/34/EU and other normative documents, regulating usage of electrical equipment in highly explosive zone.
