The most economical Solid-State TDR offered from ATC, the 329A 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 329A is the lowest cost TDR ever offered by ATC. Ruggedly designed into a 36 x 36 mm housing, the 329A 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 329A 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 329A 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 329A’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.
