Product Information

Full details

This Finder digital weekly time switch (model 12.21.8.230.0000) is designed for industrial and commercial applications requiring precise scheduling of electrical equipment. It offers quartz-controlled weekly programming with a 1-minute minimum switching time and a generous 30 memory locations, automatically handling daylight saving time changes. A key benefit is its reliable 16A/250V AC single changeover contact, though its 230V AC power requirement limits its direct use in lower voltage systems without a transformer.

FAQs

What is the shortest time I can set for a switch?

The shortest switching time for this device is 1 minute.

Does this time switch automatically adjust for daylight saving time?

Yes, this model includes automatic switching for summer/winter time adjustments.

How many different ON/OFF programs can I save?

The device has 30 memory locations to store your programmed schedules.

What is the maximum load this time switch can handle?

The single changeover contact is rated for a maximum of 16A at 250V AC.

What is the power supply requirement?

This time switch operates on a 230V AC power supply.

What does the 'autonomy' rating mean?

Autonomy refers to how long the device can maintain its programmed settings and internal clock without external power. For this model, it's approximately 6 years.

How is this device mounted?

It is designed for mounting on a standard 35mm DIN rail and occupies 2 modular spacings (35.8mm width).

Troubleshooting

Device does not power on.

Verify that the 230V AC power supply is correctly connected to the input terminals and that the power source is active.

Program schedule is not activating.

Double-check the programmed ON/OFF times and days. Ensure the shortest switching time (1 minute) is not preventing the activation. Check the program memory is not full.

LED indicators are not functioning as expected.

Consult the user manual for the specific meaning of each LED indicator. Ensure power is supplied correctly.

Device is switching at the wrong times (e.g., after power loss).

Confirm the autonomy feature (6 years) is sufficient for your expected power outage durations. If the issue persists after a long outage, the internal clock might need resetting or verification.

Pros and Cons

Pros

Reliable quartz-controlled time base for accurate scheduling.
Sufficient memory locations (30) for complex programming needs.
Automatic daylight saving time adjustment simplifies management.
High contact current capacity (16A) suitable for many loads.
Compact DIN-rail design for space-efficient installation.

Cons

Requires a 230V AC power supply, limiting direct use in 12V or 24V systems.
Shortest switching time of 1 minute may be too long for very specific micro-scheduling needs.
Programming interface may require a learning curve for new users.
Only a single channel means it can only control one set of circuits.
IP20 protection rating requires installation in a protected enclosure.

Setup, Compatibility & Care

Setup:

Ensure the power supply is disconnected.
Mount the unit onto a standard 35mm DIN rail.
Connect the 230V AC power supply to the designated terminals.
Wire the load to the changeover (SPDT) contacts according to your circuit requirements.
Refer to the user manual for detailed programming instructions to set your desired schedules.

Compatibility:

Power Supply: Requires 230V AC, 50-60Hz.
Load: Compatible with loads up to 16A at 250V AC.
Mounting: Designed for standard 35mm DIN rail.

Care:

Keep the unit clean and free from dust and moisture.
Use a dry or slightly damp cloth for cleaning; avoid solvents.
Ensure ventilation around the unit, especially when installed in an enclosure.
