DYNATIME®
Digital Series
Solid
State, PC Board Mount Hour Meters and Events Counters
|
 |
| DDS100 solid state Hour Meters have
been developed to meet the most difficult requirements
of many military and aerospace applications. In one
PCB mount package, the DDS100 provides highly reliable
means of monitoring the system. All connections are
made via printed wiring and the output brought to a
data collection point for system reading or to a single
dedicated connector.
Elapsed Time is read from
the M7793/13-1 meter by mating the printed wiring board
connections with the M7793/12-1 reader's connector and
operating the reader. Time range is 99999.99 hours.
In addition, the DDS100 has been approved to MIL-M-7793.
Cleared
by DoD/OFOISR for public release under reference number
06-S-1341 on April 20, 2006.

Elapsed Time Indicator Model
DDS100 solid state Elapsed Time Indicators have
been developed to meet the most difficult requirements of
many military and aerospace applications. In one PCB mount
package, the DDS100 provides highly reliable means of monitoring
the system. All connections are made via printed wiring and
the output brought to a data collection point for system reading
or to a single dedicated connector.
Elapsed Time is read from the M7793/13-1 meter
by mating the printed wiring board connections with the M7793/12-1
reader’s connector and operating the reader. Time range
is 99999.99 hours. In addition, the DDS100 has been approved
to MIL-M-7793/13.
Events Counter Model
The DDS101 solid state Events Counter records
counts when the unit receives power for greater than 5 seconds.
Power-on times of less than 4 seconds will not cause the counter
to increment, allowing the count to be read without affecting
the results. The count range is 9,999,999.
All connections, data collection, and the display of counts
are made in the same manner as the DDS100 Elapsed Time Indicator.
The DDS101 Event Counter meets the requirements of M7793 and
the same environmental, mechanical, and electrical specifications
as the DDS100.
