Communications
Both dry contacts (relays) that indicate status and a Serial Communications Port
(RS-232) are available for monitoring the HC-DySC.
Dry Contacts
Three relay contacts indicate HC-DySC status. The contacts are form A and
close upon occurrence of the named event: (a) any SAG EVENT, when rms input
voltage drops below 88.5% of rated value; (b) OUTPUT OK, when output
voltage remains between 87% and 110%; and (c) a system ALARM event. The
relay contact ratings are 24V at 1A.
For access, remove the small metal cover from the top of the HC-DySC
(See
Figure 6
).
