It accepts common trigger sources (positive supply, push-buttons, PNP sensors, PLC outputs) and stores settings after power-off, so it’s useful for repeated timed switching without reprogramming. The relay’s optocoupler-isolated output improves resistance to electrical interference for more reliable operation in noisy environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I set the timer and switch between modes?\u003c\/h3\u003e\n\u003cp\u003eSetting the DROK timer is done using the built-in buttons and the LED numeric display. Navigate the menu to pick one of four timing modes, then adjust the time value directly; the module saves your parameters automatically when power is removed so your configuration remains intact.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse buttons to enter mode selection and timing value screens\u003c\/li\u003e\n  \u003cli\u003eChoose between 4 available timing modes for different trigger behaviours\u003c\/li\u003e\n  \u003cli\u003eSet time from 0.1s up to 999 minutes using the digital interface\u003c\/li\u003e\n  \u003cli\u003ePower off to store settings automatically without extra steps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat trigger sources and wiring options work with this relay?\u003c\/h3\u003e\n\u003cp\u003eThe relay accepts multiple trigger types so it integrates easily into existing systems.
