The DDS200 Series solid-state panel-mount hour meters and event counters are designed to MIL-M-7793/14.
They can be read out with a companion Palm-based reader, Model DDR-1. The compact indicators permit monitoring and storing warranty or maintenance data in military and high-reliability applications where commercial-grade components are unable to survive. The indicators operate with 26 Vac or 28 Vdc and come in a 0.5-in.-sq aluminum housing. The hour meter records the time that power has been applied up to 99,999.99 hr. The event counter records the number of times that power has been applied for at least 5 sec up to 9,999,999 counts. The Palm/DDR-1 lets users take a reading, log and store the information in an Excel-compatible format on the PDA, and synchronize that file with a desktop computer. Stored information lets users identify trends, better manage warranty and maintenance data, and eliminate the need for manual records.
