1. Safety Barrier ES58 2 e Allows to create intrinsically safe circuits e Galvanic isolation of the detector line voltage e Connection of intrinsically safe detectors e Industrial plastic surface mount case e ATEX certified The Safety Barrier ES58 2 for the galvanic isolation of the detectors in the hazardous area serves for the de sign of an intrinsically safe electric circuit The plastic surface mount housing allows to mount the safety bar rier near the hazardous area The builtin zener barrier limits the current and the vol tage of the detector line as well as the electric energy stored in the intrinsically safe circuit The maximum Specifications Ignition protection number of detectors depends on the country specific regulations and can be found in the Connection of De tectors Due to the galvanic isolation the earth leakage moni toring can remain activated in the fire detection control panel Thus the installation can also be monitored in the hazardous area intrinsically safe Ex classification EEx ia IIC Operating voltage Supply through the detector line voltage Quiescent current approx mA Ambient temperature 20 C to 60 C Dimensions W x H x D 120 x 160 x 90 mm Colour light grey similar to RAL 7035 Weight 650g Approval BASEEFA98ATEX7343 Order number 228003 Order name Safety Barrier Conv ES58 2 Building Safety Building Securit2. y LABOR STRAUSS SICHERUNGSANLAGENBAU GMBH e A 1231 WIEN WIEGELESTRASSE 36 TEL 43 1 52114 0 FAX 43 1 52114 27 OFFICE LST AT WWW LST AT ALL RIGHTS RESERVED ES58 2_DBL_LST EN _0805 PDF PAGE 1
