SubscribeL-3 Communications, Electrodynamics, Inc. announces the introduction of the DDS101 solid state Event Counter that has been developed to meet the most difficult requirements of many military and aerospace applications.
The DDS101 features non-volatile memory and meets all of the requirements of MIL-M-7793/13. It provides a highly reliable means of monitoring systems' event activity.
All connections are made via printed wiring board and the output brought to a data collection point for system reading or to a single dedicated connector. Events are read from the DDS101 counter by mating the printed wiring board connections with the M7793/12-1 reader's connector and operating the reader.
Event range is 99,999 events. The output is serial binary coded decimal format. The package measures 1.1" long x .450" wide x .275" high. Weight is less than 0.2 ounces.
Environmental Specifications include operating temperature range of -65 to +125°C meets shock testing per MIL-STD-202, Method 213, Cond. I; Vibration per MIL-STD-202, Method 204, Cond. D; and life accuracy of ± 0.1% from -65 to +125°C and 4.5 to 10 VDC.
DDS101 meters meet or exceed applicable requirements of MIL-M-7793/13. Operating Voltage Range is 4.5 to 10 VDC. Ripple Voltage is 2 volt peak (4 volt peak-to-peak) ripple between 10 Hz and 10 kHz superimposed on 7.0 VDC.
Output impedance is ± 10%. Logic zero is between 0.0 and +0.2 volts. Logic one is between +3.3 and +6.6 volts. Power consumption is 2 milliwatts, max. Transient protection test subjects the DDS100 to ±25 volt transients of 10 microsecond duration occurring at a 1 millisecond repetition rate.
Delivery time is 4-6 weeks after receipt of order.
Rolling Meadows, Illinois, USA.
