Automatic Timing & Controls 800.727.5646 atcdiversified.com TIME DELAY RELAYS 329A Series Solid-State Time Delay Relay SPECIFICATIONS WIRING TYPICAL CIRCUIT ON-DELAY The 329 on-delay TDR with plug-in base maintains excellent repeat ac- curacy despite wide voltage and temperature variations. A choice of seven ranges are available from 1 second to 3 minutes. 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. CHOICE OF RANGES: The 329 is offered in a choice of seven different ranges between 1 second to 3.0 minutes to permit optimum setting ac- curacy. 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. IND. CONT . EQ. 101F 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. TERMINAL WIRING MODEL NUMBER MODEL NUMBER 329A Q RANGE
