32-Function Delay Relay 5V 12V 24V

A highly adaptable time delay relay module built around a robust microcontroller platform. Available in three fixed-input variants — DC 5 V, DC 12 V and DC 24 V — each with corresponding trigger voltage thresholds. Unit size is 78 × 56 × 25 mm; mass is 85 g. Timing range covers 0.01 seconds to 999 minutes, selectable via LED display with format auto-adjustment (hundredths, tenths, whole seconds or minutes). It implements 32 distinct timing behaviours — including delay-on-make, delay-on-break, interval, oscillation and multi-cycle sequences. Relay output is a passive SPDT contact rated for 10 A @ 30 V DC and 5 A @ 250 V AC. Standby current is 20 mA; operational draw is 60 mA. Non-volatile memory preserves all settings indefinitely after power removal. Reverse-polarity protection adds resilience during installation. Operating ambient range: -25 °C to +85 °C. Setup is fully local: K1 initiates programming mode; K2/K3 scroll and fine-tune values; K4 adjusts decimal position or disables display. Save with one K1 press. No external tools, cables or software required. Frequently deployed in smart agriculture (valve timing), building services (fan staging), packaging machinery (conveyor indexing), and retrofit automation projects where upgrading legacy electro-mechanical timers improves repeatability, reduces spare parts inventory and extends service life.
