Analog Time Switch Eti-Polam APC-D1 1P 16A 230V AC Daily is a mechanical daily timer designed for simple, reliable on/off control of electrical circuits on a 24-hour cycle. The single-pole design supports switching of lighting, heating control circuits, ventilation, or other small loads up to 16 A at 230 V AC. The timer uses a rotary dial with movable pins for setting on/off periods and does not require programming via software, making it suitable for users who prefer tactile, straightforward operation.
Advantages
The APC-D1 offers robust mechanical construction and a clear, easy-to-read dial that provides intuitive daily scheduling without electronic configuration. Its single-pole switching and 16 A rating make it compatible with many residential and light-commercial loads. The absence of digital components reduces sensitivity to voltage spikes and simplifies maintenance, while the dial-and-pin setup enables quick changes to the schedule.
Suitable for
- Daily control of indoor and outdoor lighting circuits (corridors, shop windows, façades)
- Time-based control of small heating elements, electric radiators, or convectors within rated current
- Switching fans, extractors, or ventilation systems on a daily schedule
- Simple automation tasks in residential flats, small offices, or shops
When it may not be suitable
The APC-D1 is not suitable for applications requiring multiple independent switching channels or programmable weekly/holiday schedules, since it provides only a single-pole output and a daily-only cycle. It is not the best choice for high inrush current loads such as large motors or compressors that may exceed the 16 A rating or require contactors for safe switching.
Key specifications
- Type: Mechanical analog daily time switch
- Poles: Single-pole (1P)
- Rated current: 16 A
- Supply voltage: 230 V AC, 50/60 Hz
- Control range: 24-hour dial with adjustable on/off pins
- Mounting: DIN-rail or panel (refer to installation instructions)
- Operating principle: Mechanical cam and pin scheduling
How to use
Mount the timer according to the electrical installation rules and connect live and neutral conductors to the designated terminals. Set the current time by rotating the 24-hour dial to align the marker with the present hour. Insert or remove the removable pins around the dial to define on and off intervals; each pin corresponds to a fixed time segment as marked on the dial. After setting, restore power and verify switching at the scheduled times. Regularly check contacts and mechanical parts during periodic maintenance.
What to consider before purchase
- Confirm the appliance or circuit current draw does not exceed 16 A continuous rating
- Ensure a single-pole switch meets your circuit control requirements (no neutral switching or multi-channel needs)
- Check physical mounting space and compatibility with DIN-rail or panel mounting
- Decide if a daily-only mechanical schedule is sufficient for your application
Usage recommendations
For reliable operation, use the APC-D1 with resistive or low-inrush inductive loads within its rating and, where necessary, add a contactor for switching larger appliances. Perform visual inspection of the dial and pins periodically and keep the unit free from dust and moisture to maintain accurate mechanical operation.
