Esser 803374.EX IQ8 multisensory O2T intrinsic safety detector

IQ8 multisensory O2T intrinsic safety detector. Requires connection base 805590 not included

IQ8 multisensory intrinsic safety O2T detector, equipped 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 esserbusPlus.
