Weather-based automation

The PS8A continuously collects environmental data such as wind, rain, light levels, and indoor temperature. It processes this information through configurable logic and generates switching commands that are transmitted via relay outputs to connected systems.

This enables automated control of:

• solar shading systems (awnings, blinds, louvers)

• ventilation systems

• lighting systems

• irrigation systems

A complete and integrated system

The PS8A is supplied as a complete kit, including the evaluation unit, an outdoor weather station, and an indoor temperature sensor.

The DIN-rail evaluation unit features:

• 8 freely configurable relay outputs

• AND/OR logic with adjustable thresholds

• direct programming via integrated display and keypad

No external software is required: configuration is performed directly on the device, making installation quick and intuitive.

High-performance weather station

The included P03/3 weather station ensures accurate and reliable measurements:

• light detection with separate sensors for east, south, and west façades

• twilight detection with dedicated filters

• electronic wind measurement, reliable even in extreme conditions

• heated precipitation sensor to prevent false readings caused by condensation or fog

This setup enables precise façade-based control depending on real exposure conditions.

Indoor sensor and data communication

The T-KTY82 indoor temperature sensor provides a reliable reference for control logic.

All collected data (weather, indoor temperature, and relay status) is transmitted via RS485 protocol, enabling seamless integration with PLC and BMS systems.

Installation and flexibility

The PS8A is designed for DIN-rail mounting, while the weather station can be installed on walls or poles. The system is engineered for fast commissioning thanks to direct configuration on the device and the inclusion of all necessary components.

Key benefits

• Automation based on real weather conditions

• Protection of shading systems and installations from wind and frost

• Simple integration with existing systems via relay outputs

• Fast configuration without external software

Conclusion

The PS8A is a complete and reliable solution for intelligent climate data management in buildings, combining precision, flexibility, and easy integration.
