The SB3000-Ex series isolators use optical, electrical and magnetic isolation technologies to isolate the power supply, input signal and output signal from one another, achieving isolated signal transmission between field devices and the control system. They are isolation interface units between field devices and control room equipment.<\/p>\n
The entire series is designed in accordance with GB3836.4-2000 and meets intrinsic safety explosion protection requirements. Internal isolation devices and voltage- and current-limiting components limit fault energy flowing to the hazardous area, ensuring the safety of electrical equipment and personnel in hazardous locations. The series also includes temperature transmitter models that convert various field temperature signals into standard signals, with functions covering RTD\/thermocouple\/millivolt transmitters, distributors and intermediate drive relays.<\/p>","protected":false},"excerpt":{"rendered":"
