The Curtis 2000 Series are elapsed
time indicators and counters that
deliver levels of reliability which are
orders of magnitude greater than the
parent equipment that they monitor.
MODEL 2001: Solid State Elapsed
Time Indicator. Records the time
that power has been applied up to
99,999.99 hours.
MODEL 2002: Solid State Event
Counter. Records the number of
times that power has been applied
for at least five seconds up to
99,999 counts.
MODEL 2003: Solid State Pulse
Counter. Records the number of
pulses applied to the input up to
9,999,999 pulses.
DESCRIPTION
WARRANTY
One-year replacement warranty.
Applications
The Curtis 2000 Series devices can be used to
gather use-data for warranty, design validation
and logistics support for a wide variety of military
applications, and other rugged environment
application. Records time, engine starts,
revolutions or in combination with transducers,
overstress and overtemperature hours.
Features
• Unprecedented reliability for elapsed time indi-
cators and counters - MTBF of 500,000 hours
(per MIL HDBK 217e, 50˚C, Auf environment).
This level of reliability is necessary to measure
today’s advanced electronic systems.
• EEPROM non-volatile memory ensures the
integrity of critical use data.
• Military Qualification to MIL-M-7793 (Model
2001) assures performance and makes it easy
to specify.
• Two configurations available: NT for
traditional panel mounting and PC for printed
circuit board mounting.
• NT unit allows direct readout through
MIL-M-7793/12 hand-held reader. PC unit
allows for remote reading via its serial output
(as well as with hand-held reader).
• High resolution, long range, small size and
low power permits the use of a 2000 Series
device across the total spectrum of equipment
and systems.
• Available for 5VDC, 28VDC/26VAC and
115VAC operation - satisfies the predominant
military and industrial system operating
voltages.
• Model 2003 accepts pulses of 1 millisecond
on (min.), 1 millisecond off (min.) and rejects
any pulses under 0.75 milliseconds as a
transient or error.
