Müller SC 38.20 pro5 temporizador digital 12-24 V AC/DC 600 W carril DIN 2 canales programa semanal 24784

The Müller SC 38.20 pro5 stands apart with its dual-channel control and 50-program memory, enabling independent scheduling of two circuits from a single DIN rail unit. Its 12-24 V AC/DC operating range suits low-voltage installations where typical 230 V timers cannot be used.

Highlights

• Two channels with 50 ON/OFF programs for flexible weekly scheduling
• Wide 12-24 V AC/DC supply voltage for low-voltage systems
• High switching capacity: 16 A / 250 V AC per channel, 600 W LED load
• 5-year lithium battery power reserve maintains settings during outages
• Automatic summer/winter time changeover and holiday program
• Manual override and PIN code protection for secure operation
• Zero-crossing switching reduces inrush current and extends relay life

In daily use

Program up to 50 ON/OFF events per week with 1-minute resolution. The LCD shows current time and program status, while manual override lets you temporarily change state without altering stored programs. PIN protection prevents unauthorized changes. The zero-crossing switching minimizes contact wear, making it suitable for frequent switching of LED lighting.
