DC 12V time delay relay module with 8 time ranges from 1 second to 1 hour. It supports delay on and delay off control for a variety of applications. Key benefits Flexible timing options: eight time ranges allow precise control from 1 s up to 1 h to suit different tasks. Reliable load switching: compatible with up to 250V AC 10A or 30V DC 10A loads, enabling use with common equipment while protecting connected devices. Simple time setup: a delay adjustment potentiometer lets you set the required delay quickly; rotate the potentiometer clockwise to extend the delay time. Clear control of start and stop sequences: enables both delay on and delay off operations to fit automation needs. Specifications at a glance Supply voltage: DC 12V Timing ranges: 8 options, 1 second to 1 hour Relay load capacity: up to 250V AC 10A or 30V DC 10A Control mode: delay on or delay off Adjustment: delay time set via a potentiometer; clockwise increases delay Applications and use scenarios Industrial automation: use to stagger machine start sequences, reducing inrush current and wear on power circuits. Lighting and signage: implement delay on for entrance lights or delayed off for signage to save energy. Heating, ventilation, and cooling: control fans or heaters with a safe startup delay or timed shutdown to maintain stable operation. Notes This module is designed for DC 12V operation and supports standard AC and DC loads within its rated limits. Time is adjusted via the external potentiometer; ensure correct wiring and safety practices when integrating into circuits.
