HD5500 DIN rail 4-20mA signal isolator switch

HD5500 series isolated barriers are designed explicitly according to latest national standard for protection of electrical signals located in hazardous areas.
Installed in safe areas, HD5500 series Isolated barriers work in company with intrinsically safe instruments located in hazardous areas to guarantee a totally IS explosion protection system. With the inside signal transfer module, HD5500 series isolated barriers can also play the roles of RTD temperature transmitter, thermocouple temperature transmitter and mV transmitter, as well as repeater power supply, solenoid driver and so on.
Features
 No high-integrity earth needed
HD5500 series Isolated 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 compact modular design, HD5500 series isolated barriers provide wide application range in the minimum space.

Standard DIN-rail mounting and PLUG & PLAY terminals
Standard DIN rail mounting format ensures convenient and steady installation, while application of PLUG & PLAY connector ensures the convenience of maintenance.
