TIG telephone
Intrinsically Safe Telephones TIG
Application TIG intrinsically safe telephone sets operating in UTI, PTI, LSTI-A, STG systems have been designed for exploitation in hard industrial conditions, including mining (extensive humidity, noise, dustiness, explosion hazard) in rooms of I group of explosion, category M1 and II group, categories 1, 2 and 3.
Cooperation
With the station equipment of UTI, PTI, LSTI-A, STG devices, through the unit of intrinsically safe separation ZSD, ZSI.
Power supply
Central from UTI, PTI, LSTI-A, STG devices.
