A Safe Way In Automation
AD-STC1
HART Smart Transmitter Intrinsic Safety Barrier(1-Channel)
The AD-STC is an intrinsically safe barrier, designed with 1 or 2 channel(s) for reading 2-wire smart transmitters in hazardous areas. It reads data from hazardous areas through a 4 ~ 20 mA analog current signal via the HART protocol, which it then transfers to the safe area. After that, the collected data at the safe area is transmitted to the station, through a reproduced analog signal similar to the one in the hazardous area.
Moreover, digital signals may be superimposed on the input signal in the hazardous or safe area, which it then transfers bi-directionally. The current and power consumption of the input is about 208 mA and 5W, respectively, and the power dissipation is less than 1W. The environmental conditions are -20 to +60 °C as an operation and -25 to +65 °C as storage temperature. The AD-STC is mounted on a sturdy 35 mm DIN mounting rail acc.
