GS8500-EX range functional safety isolated barriers are CHENZHU's hit products, which obtained the first IECEx, ATEX, DE TUV SIL, JP TIIS certifications in domestic China, offering the widest selection of products such as GS-8500 EX analog intrinsic safety isolator for the protection of electrical signals, meets the intrinsic safety standards for both explosive gas and dust environment, widely used in the control system of petroleum and petrochemical, railways, coal mines, and other industries.
To achieve safety automation system, you can trust CHENZHU! Do not hesitate to contact us.
The isolated barrier requires independent 24V power supply.
There is no need for an external power supply. The signal acquisition loop and the power distribution loop share one loop.
The output is loop powered. It outputs passive signals, which need DCS/PLC to provide external power supply.
High adaptability for electromagnetic environment, compliance with EMC standard: IEC61326-3-1
Awarded CCC /IECEx/ATEX certification
Intrinsic safety standards for explosive gas/dust environment
Can be installed in Zone 2 environment
Certified by TÜV Rheinland for SIL3 application
Compliance with G3 anti-corrosion level
