Digital individual ground alarm SZITS-D-L with an additory diapason and supervisory monitoring is of use as electric main critical insulation resistance control which is powered by a single electric power supply.
The device is resistant to interference that is why it may be used as linear chains dielectric resistance control and in regulation lights control circuits which are exposed to interfering signals the most by centralized installation.
Designated area: functioning and going up automatic – and communication installations.
Similar equipment: SZITZ-D.
resistance to interference in long linear chains
dielectric resistance status data transfer possibility to the dispatch control system
all types of electric power supply have equal manufacturing
high fire safety of the device
DC power supply sides insensitivity low effect (force)
low insensitivity dancing by connection voltage – and tasting voltage excursion
there exists the possibility of an in field testing the attention device sensitivity
application possibility of changing in direction of movements in diagrams
