Esser 803271.EX IQ8 intrinsic safety thermovelocimetric…

IQ8 intrinsic safety thermovelocimetric detector. Requires connection base 805590 not included

IQ8 intrinsic safety thermovelocimetric detector, provided with

individual microprocessor operating in intelligence systems

distributed, self-test function, CPU fault mode, data memory

alarm and operation, alarm indication, addressing by

software and indication of type of operation, when connected to a loop

esserbus or esserbus Plus. The detector does not incorporate a short-circuit isolator

loop, to allow its operation in conventional mode, within

intrinsically safe zones, connected through the safety barrier

intrinsic 764744 to conventional transponder zone 808623. Specification

EN54-5 A1. Requires connection base 805590 not included.

For connection in conventional mode in intrinsically safe areas,

precise:

-Intrinsic safety barrier 764744.

-Transponder 808623 For its connection to the analog loop, it requires the barrier

804744. Accurate base 805590.
