The GS8500-EX series ultra-thin isolated safety barrier uses a customized shell from Phoenix Contact in Germany, with a thickness of only 12.5mm, making it the thinnest product of its kind in the world. In terms of circuit design, the GS8500-EX functional safety isolation barrier uses a new plate type transformer instead of the traditional ring transformer, further enhancing anti-interference performance and consistency of signal coupling. Adopting low-power technology to reduce power consumption. In addition, functional safety technology is introduced in accordance with the IEC 615508 standard during the research and design process to improve product reliability and safety, achieving SIL2 and SIL3 levels. Realize independent power supply from the power terminal and optional power supply from the power bus.
