335B-351-A-10PX timer relay from Marsh Bellofram’s ATC line is a 120 V AC, 60 Hz timing device that provides a controlled delay from 0 to 99.99 seconds. This electronic timer relay is used to introduce precise sequencing in industrial control circuits, such as interlocks and start/stop routines, by energizing its output after the set interval. The model sits within ATC’s timer family and is commonly employed in manufacturing and process-control panels where repeatable delays are required to coordinate multiple loads or devices via standard relay configurations.
