The most economical Solid-State TDR offered from ATC, the 329 on-delay
TDR with plug-in base maintains excellent repeat accuracy despite wide
voltage and temperature variations. A choice of eight fixed ranges are
available from 0.3 seconds to 3 minutes.
Price/Performance Value: The economical 329 is the lowest cost TDR ever
offered by ATC. Ruggedly designed into a 36 x 36 mm housing, the 329
On-Delay TDR combines both highly accurate and repeatable timing with
industrial quality that is usually found in only the more expensive timers.
CHOICE OF RANGES: The 329 is offered in a choice of eight different fixed
ranges between 0.3 seconds to 3.0 minutes to permit optimum setting
accuracy. The dial face clearly displays the range.
DESIGNED FOR INDUSTRIAL SERVICE: The 329 incorporates features
designed to ensure a long trouble-free life expectancy, even in difficult
industrial environments: high impact resistant housing with octal plug-in
base that is easily surface/DIN or panel mounted; a DPDT 5 amp relay rated
for 10 million operations at no load; and an oscillator-based timing circuit
for high accuracy even with changes in temperature and voltage.
HIGH ACCURACY: The 329’s timing circuit is not a simple RC circuit, but it
utilizes the sophistication of a proprietary integrated circuit that includes
counting technology along with a stable oscillator to provide repeatable
time delays.
Timing begins when the start switch is closed. This starts an oscillator
which runs at a frequency determined by the time setting. A fixed number
of counts from the oscillator determines the end of the time cycle. The
time required to accomplish this depends on the oscillator frequency.

At time out, the built-in relay transfers its contacts. These contacts remain
transferred until the start switch is opened or power is removed by some
other means. The 329 then resets and is ready for another cycle.
