Weekly digital 2-channel timer D22 412641

Precise time control for professional installations

The D22 weekly digital programmer is an advanced device for automatic control of electrical circuits in domestic and industrial installations. Two independent channels allow for simultaneous management of different systems - from lighting to heating and building automation. Mounting on a standard DIN rail (2 modules) ensures easy integration with existing switchboards.

Advanced programming functions and operational flexibility

The device offers comprehensive programming capabilities: daily, weekly, and annual programs with support for holidays and vacations. 56 memory slots enable the creation of extensive schedules, and the random program function simulates presence in the home. The cyclic program is ideal for applications requiring repetitive sequences.

Quartz accuracy of ±0.1s/day guarantees reliable operation with 5 years of autonomy. Automatic daylight saving time adjustment eliminates the need for manual correction. Manual override allows for immediate switching without interrupting programmed sequences.

Electrical parameters and operational safety

The programmer operates at a voltage of 230V AC ±50/60Hz, supporting loads up to 16A at 250V AC. NO/NC changeover contacts ensure connection versatility - it is possible to control both live receivers and volt-free circuits.

The shortest switching time is just 0.01666s, enabling precise control even of fast processes. The built-in hour meter allows monitoring of the operating time of connected devices - useful for maintenance and energy billing.

Construction and operating conditions

The compact housing (35.6×83×60mm) made in grey (RAL 7035) is characterized by an IP20 protection class. The device operates in temperatures from -20°C to +55°C, with storage possible in the range of -20°C to +60°C.

The halogen-free design with marked screw terminals (wire gauge 1.5-4mm²) facilitates professional installation. The integrated lithium battery (CR2477) ensures long-term operation of the emergency power supply system.
