The DDS101 solid state event counter from L-3 Communications/Electrodynamics Inc. has a nonvolatile memory that holds up to 99,999 events and outputs them into serial, binary-coded decimal format to a data collection point for system reading or to a single dedicated connector.

The 27.94-by-11.43-by-6.98mm PCB-mounted device satisfies the requirements of the MIL-M-7793/13 standard. Events are read from the counter by mating the printed wiring board connections with the M7793/12-1 reader's connector and the operating reader.

It operates from a 4.5Vdc to 10Vdc supply and produces a ripple voltage of 4Vpp between 10Hz and 10kHz superimposed on 7Vdc. Logic zero is between 0V and 0.2V, while logic one is between 3.3V and 6.6V.

The device consumes 2mW and is protected from transients up to 125V.

The DDS101 is priced at $125 or less depending on volume.
