Designed to save your configured settings automatically and to resist electrical interference, it is useful for lighting holdoffs, motor cycling, automation sequences, and delayed shutdowns where precise timing and a compact footprint matter.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I choose the right timing mode for my project?\u003c\/h3\u003e\n\u003cp\u003ePick the mode based on whether you need the relay to switch on then off, hold on after the trigger, or behave in latch-style operation. Each of the four modes maps to common control patterns found in automotive and small automation systems, so match the mode to the desired on\/off timing behavior.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMode A: immediate output on trigger, then off after set delay\u003c\/li\u003e\n  \u003cli\u003eMode B: delayed turn-on after trigger, then stays on\u003c\/li\u003e\n  \u003cli\u003eMode C: single pulse or latch pattern depending on wiring\u003c\/li\u003e\n  \u003cli\u003eMode D: custom on\/off timing for cyclic or safety applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat timing range and resolution can I expect?\u003c\/h3\u003e\n\u003cp\u003eThe DROK relay covers a wide span from very short pulses to long delays, letting you dial in fine or coarse intervals for diverse tasks.
