Programmable Timer MDT SCN-RTC20.02 — 20 channels, color display, 4TE DIN module

MDT SCN-RTC20.02 is a programmable DIN-rail timer offering 20 independent channels in a compact 4TE module with a color display. It is designed for automation tasks where multiple time-controlled outputs are required, providing clear visual status and easy scheduling for lighting, HVAC, pumps and similar building systems in residential and commercial installations.

Advantages

The device combines a high channel count with a small footprint, allowing centralized time control without occupying excessive DIN-rail space. The color display gives immediate visual feedback on channel states and scheduling, while independent channel programming supports varied daily and weekly schedules. Its design focuses on reliable time-based switching and straightforward integration into standard electrical enclosures.

Suitable for

• Scheduled lighting control in homes, offices and public buildings
• Time-based operation of heating, ventilation and air-conditioning equipment
• Pump control for irrigation, water supply and circulation systems
• Timed control of sockets, relays and small loads in automation panels
• Centralized scheduling where multiple independent outputs are required

Key specifications

• 20 independent programmable channels for timed switching
• Color display for status indication and programming
• Compact 4TE DIN-rail module for space-efficient installation
• Support for daily and weekly scheduling with multiple switching events per channel
• Manual override options and clear visual status for each channel
• Designed for integration into residential and commercial electrical panels

How to use

Install the unit on a standard DIN rail inside the electrical enclosure and connect outputs to the loads according to the wiring diagram. Use the color display and built-in menu to create and assign schedules to each of the 20 channels, specifying on/off times and the required days of operation. Verify clock and calendar settings before activating schedules. Manual override functions allow temporary switching without changing programmed schedules.

Usage recommendations

Set the device clock to the correct local time and confirm daylight saving settings if applicable. Group loads by usage pattern to optimize channel assignment and minimize unnecessary switching. Periodically check and back up schedule settings after major changes to ensure consistent operation. For safety, follow local electrical codes and isolate supply before installation or maintenance.
