800.727.5646 automatictiming.com Automatic Timing & Controls 319 Series Time Delay Relays // 319 Series 51 An economical 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 dialselected adjustable ranges and provides any timing period between 0.02 SEC and 30 MIN; Lower-cost models incorporate three dials elected ranges or a single adjustable range. WIDE CHOICE OF RANGES: In addition to the short ranges expected of an electronic TDR, the 319E is also available with ranges as long as 100 minutes, for AC or DC operation. An unusually versatile model, the 319E five ranger has five dial-selected ranges—from 0.3 SEC to 30 MIN—and provides any dial-adjustable timing period between 0.02 seconds and 30 minutes; (1, 10 and 100 SEC and 10 and 100 MIN). A single 319E model thus accommodates the needs of a wide range of applications, allowing the user to select--easily and precisely--an appropriate range to permit optimum setting accuracy. The dial face automatically displays the selected range. The 319 offers a choice of five dial-adjustable fixed ranges between 1 SEC and 30 SEC. CYCLE PROGRESS INDICATION—MODEL 319E: All options incorporate a lightemitting diode (LED) which is on during the time cycle, off at the end of timing. The 5-range option also includes a second LED which separately indicates the status of the output relay: on when energized, off when de-energized. HIGH ACCURACY: The 319’s timing circuit is not subject to the large plus error that plagues many electronic TDRs after long periods of down-time: it maintains rated accuracy regardless of reset time variations, provided that there is at least 0.1 SEC between cycles for Model 319E. All models hold unusually high repeat accuracy in the face of wide voltage and temperature swings. Timing begins when the start switch is closed. At the same time, the Timing LED goes on and a relaxation oscillator starts to run at a rate determined by the set-pot. The 319E times out when the 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.
