⻬ Provides Eight
Independent Relay
Contact Outputs
⻬ Requires Minimal
System Power
The OMB-DBK25 8-channel
relay-output card provides
OMEGA’s OMB-LOGBOOK
and OMB-DAQBOARD-2000 Series
data acquisition systems with eight
fully independent relay contact
outputs. Because the OMB-DBK25
is designed for use in portable as
well as desktop applications, it
employs miniature latch relays that
draw power only when changing
states,
i.e.
, when changing from off
to on or from on to off. This minimal
power consumption makes the
OMB-DBK25 ideal for applications
that rely on battery power. The
OMB-DBK25 relay contacts are
rated for 2 A at 28 Vdc or 0.6 A at
120 Vac. As many as twenty-four
OMB-DBK25’s can be used in one
system, to obtain 192 outputs.
