Through advanced circuit design and packaging technology, the ON-Delay ATC 313A packs all of the performance of a conventional plug-in TDR in a space-saving housing. It features a digital timing circuit which ensures high repeat accuracy and excellent noise immunity.

The ATC 314B is an economical multi-range solid-state TDR with two models; one for off-delay (delay-on-break) and one for interval-on-delay operation. With three dial-selected adjustable ranges, it provides any timing period between 0.035 and 100 SEC with excellent repeat accuracy even with wide changes in voltage, temperature and reset time.

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 dial-selected 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.

The 328D Directly replaces the 328A, B, and C. An extremely versatile dial-adjustable time delay relay, the ATC 328 provides a choice of ON-delay, OFF-delay or interval operation for any timing period between 50 ms and 10 hours...all in the same timer. Based on a unique digital circuit, it features cycle progress annunciation and is suitable for the most demanding industrial service.

The most economical Solid-State TDR offered from ATC, the ATC 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.

An economical solid-state TDR with octal plug-in base, the ATC 339A maintains excellent repeat accuracy despite wide voltage and temperature variations. even after long periods of down-time. Two models are available. Each has six dial selected ranges from fractions of a second to as long as 10 hours. Each model has a selectable on-delay or interval timing mode.

The ATC 342 is a repeat cycle panel mounted timer with two separately adjustable On and Off times. Designed with a heavy duty DPDT 7A Relay, the 342 can cycle a load On and Off repeatedly as long as the timer is powered. Time ranges from 50ms to 10 Hrs. are knob selectable. Operating voltage is universal.
