Spark protection barriers with galvanic isolation EnI - BIS - 3220 - Ex - AI, EnI - BIS - 3230 - Ех - АI
EnI - BIS - 3220 - Ex - AI - is a single - or two - channel active spark protection barrier with galvanic isolation. .
EnI - BIS - 3230 - Ex - АI - is a single - or two - channel active spark protection barrier with galvanic isolation in a compact package.
The barriers ensure the transmission of the current signal and the HART - protocol signal from the explosive zone to the explosion - proof one.
The barriers provide bidirectional transmission of a digital signal over the HART protocol.
Искробезопасные барьеры обеспечивают питание датчика и нагрузки.
Barriers are designed to be placed outside an explosive zone.
Advantages of galvanic isolation barriers:
- without grounding;
- high noise immunity;
- conversion of signals;
- use of a power supply with an output voltage greater than Uo;
- maintaining the operability of fuses in case of short - circuit of intrinsically safe circuits;
- allow you to use a single power source for multiple circuits.
Galvanic isolation barriers are designed to connect sensors with 4.20/0.20 ma output current signals and a digital signal based on the HART protocol located in an explosive zone.
Depending on the design, the spark protection barriers are designed to work with both active sensors and loads, as well as with passive ones.
