Supply SB3000-Ex series of isolation barrier. SB3000-Ex series of isolation barrier through the optical, electrical, magnetic and other isolation technology on the power supply, input signal and output signal of the two isolation, in order to achieve the field device and control system between the isolated signal transmission, Isolation equipment and control room equipment between the isolation interface unit; isolation technology on the input and output signals in the electrical isolation, greatly improving the anti-jamming and reliability of electronic systems, the current more and more industrial control systems and field equipment Of the interface using isolated interface unit to replace the original non-isolated unit. SB3000-Ex series of isolation barrier are designed according to GB3836.4-2001-66368525, in line with the safety requirements, with strict isolation capacity, it is installed in a safe place, and installed in a dangerous place of intrinsically safe explosion-proof equipment together Safe explosion - proof system. The use of internal isolation devices, pressure limiting, current limiting components to limit the flow of dangerous energy to the dangerous area, so as to ensure the safety of electrical equipment and personal safety. The SB3000-Ex series of isolation barriers also includes temperature transmitter models that convert a wide range of temperature measurement physical signals into standard signals. The full range of isolated safety barriers covers the following functions: Thermal resistance temperature signal transmitter , Millivolt signal transmitter, thermocouple temperature signal transmitter, power distribution and intermediate drive relays. SB3016-EX, SB3016 / R-EX, SB3017 / R-Ex for the two-channel switch / proximity switch input type, relay contact output type, NPN transistor OC gate output type isolation safety barrier; SB3025-EX, SB3026-EX SB3041-Ex, SB3043-Ex, SB3041-Ex, SB3041-Ex, SB3041-Ex, SB3041-Ex, SB3041-Ex, SB3041-Ex, SB3041-Ex, SB3041-Ex, SB3045-Ex, SB3045-Ex, SB3045-Ex, SB3075-Ex, SB3045-Ex, SB3045-Ex, SB3045-Ex, SB3045-Ex, SB3045-Ex, SB3045-Ex, AC-type isolation barrier; SB3081-EX, SB3084-EX, SB3447-EX are millivolt signal transmission type, resistance signal transmission type, current input alarm set isolation barrier.
