B-SAFE3 Intrinsically Safe Power Supply
Cod.: AC.012.100 + -
B-SAFE3 is an ATEX-certified intrinsically safe barrier designed to protect and isolate electrical circuits between hazardous and safe areas. The device is intended to separate and protect spark-safe circuits (devices in explosive environments) from other external circuits.
It serves as a crucial interface for power supply and data communication in environments where explosive gases, vapors, or dust may be present.
By preventing excessive energy transfer, B-SAFE3 ensures that no sparks or thermal effects can ignite the hazardous atmosphere, making it a key safety component in industrial operations. B-SAFE3 facilitates secure and efficient RS485 communication and digital input processing while maintaining strict compliance with ATEX regulations.
This device acts as an intrinsically safe separator for the communication circuits of conversion devices, allowing the connection of standard devices for reading/writing data via RS485 communication, such as PCs, PLC automation systems, external modems, or flow computers/intrinsically safe dataloggers.
