The points of HD5500 safety barrier

All units with IP20 degree of mechanical protection are compliant to GB3836.1-2010 (IEC60079-0: 2007, MOD) and GB3836.4-2010(IEC60079-11: 2006, MOD), and certified for connection into Zone0, Zone1, Zone2, Zone10, Zone11, ⅡC, ⅡB, ⅡA, T1-T6 hazardous areas worldwide.

No high-integrity earth needed
HD5500 series safety barriers need no dedicated ground and consequently eliminate the inherent interference of ground loop.

Full input/output/power supply isolation
Full 3-port isolation between the input, output and power supply circuits achieves highly floating systems for the pursuit of extraordinary resistibility to complicated electromagnetic interference from industrial environment.

High-performance components
High-performance components are widely adopted for optimal signal integrity, taking into account both high accuracy and low drift of full range.

Compact modular design
With the compact modular design, HD5500 series isolated barriers provide a wide application range in the minimum space.

Standard DIN-rail mounting and PLUG & PLAY terminals
Standard DIN rail mounting format ensures convenient and steady in.
