DZW-3 - Flameproof Local Monitor
Flameproof local monitor DZW-3/* is designed to display images from one CCTV camera in hazardous conditions of methane and / or coal dust explosion, giving possibility to observe objects and work carried out in zones with danger of explosion. Depending on the version, the input signal can be intrinsically safe electrical or optical in Composite Video standard (CVBS). Input is prepared to connect coaxial cable 75Ω (in version DZW- 3/CC), UTP cable 110Ω (in version DZW-3/CT) or SM fiber optic cable (in version DZW-3/SM). The image is presented on LCD 7" display. The monitor includes modules closed in flameproof casing and requires intrinsically safe supply voltage from 12 to 15 VDC. The equipment of Flameproof Local Monitor was designed with components dedicated to work in hard environment conditions.
