Spark protection barriers with galvanic isolation EnI-BIS-300-Ex

Spark protection barriers with galvanic isolation are intrinsic safety barriers with galvanic separation of spark - hazardous and intrinsically safe circuits, combining a passive (shunt - diode) spark protection barrier and a signal converter.

The barrier, depending on the type, contains intrinsically safe electrical circuits made with the level of explosion protection "ia" - "especially explosion - proof". Barriers meet the requirements of GOST 31610.0, GOST 31610.11 for subgroups IIB, IIC.

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.

Model range of active barriers with galvanic isolation: Eni - BIS - 301, 302 - Ex - AI - 1K, Eni - BIS - 310 - Ex - DI - 1K, Eni - BIS - 320 - Ex - AI - 1K - N.

Organization of power supply and reception of information signals 4.. .20 mA DC via a two - wire line from sensors that are made with explosion protection of the "intrinsically safe electrical circuit" type. Conversion of the input unified current signal 4.. .20 mA to the output signals 0.. .5 mA, 0.. .20 mA or 4.. .20 mA. Connection of sensors with discrete output signals, including circuit monitoring, sensors with NAMUR EN output signal 60947 - 5 - 6.
