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.

Features

• Monitors your system usage
• PCB Mount
• Non-Volatile Memory

• RS232/TTL output option available
• 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.

Electrical Specifications

The meters meet or exceed applicable requirements of MIL-M-7793 M7793/13. Other ratings and configurations are also available.
