Hazardous area Low Current LED Panel Lamp Fieldbus intrinsically safe digital output module Intrinsically safe for use in all gas and dust hazardous areas Fieldbus IECEx, ATEX & FM certification. u Red, amber, green, BA390S low current panel lamps provide reliable, cost effective visual status indication in all gas and dust hazardous areas. Each BA390S lamp produces a uniform output with just a few milliamps of input current and has a typical life greater than ten years. Optimised for use at low currents BA390S lamps may be powered from almost any intrinsically safe supply. Their high efficiency results in a useful visible output with an input current of only a few milliamps. Lamps can therefore be powered from a current limited intrinsically safe supply, such as a digital output on a multiple output fieldbus module. Several lamps can also be powered, with suitable current limiting, from a Zener barrier or galvanic isolator. IECEx and ATEX intrinsic safety certification permits BA390S LED panel lamps to be installed in all gas and dust hazardous areas. For use in the USA all models also have FM gas certification. Five well defined lamp colours - red, amber, green, blue and white allow lamps to be selected to comply with the indicator light colours recommended by IEC 73. When not powered, the front of panel coloured diffuser enables the lamp colour to be easily identified. IP66 sealing of the lamp front and the joint between the lamp and the panel enclosure, enable BA390S lamps to be successfully installed in areas that will be hosed, washed or splashed. When rear of panel environmental protection is also required, the optional BA599 rear sealing kit provides IP66 protection and includes a cable gland to seal and support the supply cable. Mounting is via a single industry standard 22.5mm diameter hole. The lamp housing, fixing nut and terminals have a maximum diameter of 30mm which permits a very high packing density on the panel. To aid identification from the rear of the panel, the model number and suffix which identifies the colour are marked on the lamp body close to the terminals Reliability is ensured by an ISO9001 approved quality control system supported by a three year guarantee. blue & white models. u perates from any O current limited intrinsically safe source u IP66 front u 3 year guarantee www.beka.co.uk/ba390s Complementary certified panel lamps incorporating an internal 20mA current regulator that may be powered directly from a Zener barrier or galvanic isolator are also available, please see BA390 datasheet. For safe area applications, the uncertified BA590 lamps incorporate a 20mA regulator and have similar features as the BA390 lamps. BEKA associates Ltd. Old Charlton Rd.
