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.
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.

Features
• Unprecedented reliability for elapsed time indi-
cators and counters - MTBF of 500,000 hours
(per MIL HDBK 217e, 50˚C, A
uf
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.
One-year replacement warranty.
