Finder 12.B2.8.230.0000 Annual Astronomical Digital Time Switch 2-Pole 16A 230V AC/DC with Expandable I/O

The Finder 12.B2.8.230.0000 is a high-precision annual astronomical digital time switch engineered for sophisticated scheduling and automation. This 2-pole device, rated for 16A and 230V AC/DC operation, provides reliable control for electrical systems that require long-term astronomical timing, such as lighting circuits or energy management infrastructure. Its design allows for expandable inputs and outputs, making it a versatile solution for complex professional installations.

Advantages

This digital time switch offers exceptional flexibility through its annual programming capabilities, allowing users to set schedules that adapt to seasonal changes automatically based on astronomical data. The inclusion of expandable I/O options ensures that the system can grow with the requirements of the installation, providing a scalable solution for advanced automation. Its robust 16A 2-pole configuration ensures compatibility with a wide range of electrical loads, while the 230V AC/DC power supply provides operational versatility across different power environments.

Suitable for

• Public and street lighting control systems
• Commercial building energy management
• Automated garden and landscape illumination
• Complex industrial timing and scheduling tasks
• Seasonal signage and display lighting

When it may not be suitable

This device is designed for professional electrical installations and may be overly complex for simple residential applications that only require basic daily timers. It is not intended for use in environments where the specific astronomical location data cannot be accurately configured or where high-frequency switching exceeds the mechanical and electrical ratings of the relay.

Key specifications

• Switching capacity: 16A
• Number of poles: 2
• Operating voltage: 230V AC/DC
• Functionality: Annual astronomical scheduling
• Expandability: Supports additional inputs and outputs

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within an electrical distribution board. Once powered, the unit is configured via its digital interface to set the geographical location, which allows the internal astronomical clock to calculate sunrise and sunset times accurately. Users can then program specific switching events or offsets to meet the requirements of the connected load.

What to consider before purchase

• Ensure the electrical load does not exceed the 16A rating
• Verify that the installation environment is suitable for DIN rail mounting
• Confirm that the required astronomical features align with your project needs
• Check if additional I/O modules are necessary for your specific automation setup

Usage recommendations

For optimal performance and longevity, ensure the device is housed in an enclosure that protects it from extreme moisture and dust. Regularly verify the time settings and geographical coordinates if the system experiences power loss or if seasonal adjustments are required.
