Gira kytkentä- ja verhoilutoimilaite 6f/3f 16 A 502300

The Gira 502300 combines six independent switching channels and three blind/shutter channels in a single 4-module DIN rail device, giving KNX installations a space-saving way to control both lighting and motorised blinds from one actuator. Unlike separate switching and blind actuators, this unit reduces wiring and bus device count while keeping manual override buttons on the front for testing and commissioning.

Highlights

• 6 switching channels, each rated 16 A for ohmic loads up to 3680 W at 230 V AC
• 3 blind/shutter channels for 230 V AC motors, each up to 1380 VA
• Manual operation via push buttons directly on the device
• Integrated logic functions: scenes, time functions, staircase lighting
• Status feedback over KNX bus
• Overload protection per channel
• Compact 4 TE (DIN modules) width for DIN rail mounting

In daily use

Configured entirely through ETS, the actuator responds to KNX telegrams for switching, blind positioning, slat adjustment, and scene recall. The manual buttons allow local control during installation or in case of bus failure. Screw terminals accept solid or stranded conductors, and the device is powered solely from the KNX bus (21–30 V DC), so no auxiliary supply is needed.

Final note

For projects where both lighting and blinds must be automated on a single KNX line, the 502300 offers a practical balance of channel count and panel space.
