| Datasheet | Download Datasheet |
The TimeMark 553-02 is a re-acceleration relay for 120 V AC systems. Once the start switch is closed its contact closes after the on-delay. If the voltage drops below 90 V AC the contact opens, and it re-closes by itself only if the voltage recovers within the true-off delay; otherwise it waits for the start switch.
Trip points: drop-out 90 V AC (fixed); pick-up 102 V AC (fixed). Trip delay: 100 ms. Pick-up delay: 1-120 s (adjustable on-delay). Reset: automatic within the true-off delay (1-10 s, adjustable); otherwise by the start switch.
Mounting: plug-in.
