The 329 on-delay TDR with plug-in base maintains excellent repeat accuracy despite wide voltage and temperature variations.
Performance Value
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.
Range
The 329 is comes with 3 minutes range 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 oscillatorwhich runs at a frequency determined by the time setting. A fixed number of counts from the oscillator determines the end of the time cycle. Thetime 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.
