GIRA KNX Bus Coupler 3 External Sensors 200900

KNX bus coupler with three universal inputs for integrating conventional switches, push-buttons, or external sensors into a KNX installation. Each input can be configured for switching, dimming, blind control, value transmission, scene recall, or temperature measurement.

Advantages

Flexible input configuration supports potential-free contacts, NTC temperature sensors, and PT1000 temperature sensors. Built-in logic functions (AND, OR, XOR, gate) and threshold monitoring enable advanced automation scenarios without additional modules. Powered directly from the KNX bus, requiring no separate power supply.

Suitable for

• Retrofitting conventional switches and push-buttons into KNX smart home systems
• Connecting temperature sensors for room climate control
• Implementing complex logic and scene control in building automation
