ATC 319E-030-F-1-C Plug-in Adjustable AC/DC Solid-State TDR, 24-240 VAC, 24 VDC, On-Delay, Standard

An economical ON-delay solid state TDR with octal plug-in base the ATC 319 maintains excellent repeat accuracy despite wide voltage and temperature variations, even after long periods of down-time. One model has five dial-selected adjustable ranges and provides any timing period between 0.02 SEC and 30 MIN; Lower cost models incorporate three dial selected ranges or a single adjustable range. Operations: Timing begins when the start switch is closed. At the same time, the Timing LED goes on and a relaxation oscillator count is equal to the level set by the range switch, a second LED turns on at time-out. At time-out, the load relay is energized, transferring its contacts. Reset occurs when the start switch is opened or when power is interrupted.

• Five dial-selected ranges: 0.3 SEC., 3 SEC., 30 SEC., 3 MIN., 30 MIN
• Wide Choice of Ranges: In addition to the short ranges expected of an electronic TDR, the 319 is also available with ranges as long as 100 minutes, for AC or DC operation
• An unusually versatile model, the 319 five ranger has five dial-selected rangers, from 0.3 SEC to 30 MIN, and provides any dial=adjustable timing period between 0.02 seconds and 30 minutes
• All options incorporate a light-emitting diode (LED) which is on during the time cycle, off at the end of timing
• The 319's timing circuit is not subject to the large plus error that plagues many electronic TDRs after a long periods of downtime
