SB3000-Ex Series Isolated Barriers

Installed in safe areas, SB3000-EX 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, SB3000-EX 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.
No high-integrity earth needed - SB3000-EX series Isolated barriers need no dedicated ground and consequently eliminate the inherent interference of ground loop.
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, SB3000-EX series isolated barriers provide wide application range in the minimum space.

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.

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.
