Solid
State, PC Board Mount Elapsed Time
Indicators Monitors your system usage
ROLLING MEADOWS, ILLINOIS,
USA. L-3 Communications, Electrodynamics, Inc. announces
the introduction of the DDS100 solid state Elapsed Time Indicator
that has been developed to meet the most difficult requirements
of many military and aerospace applications. Qualified to
MIL-M-7793/13, the DDS100 provides a highly reliable means
of monitoring systems' elapsed time and features non-volatile
memory. 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. 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. In addition, the DDS100 has been approved
to MIL-M-7793. Other options available such as Event Counter
and RS232/TTL output.
Time range
is 99999.99 hours. Meter 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.
DDS100
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.
