GIRA KNX Switching Actuator 2-Channel 16A DIN Rail 104000

For KNX installations that demand compact, high-current switching without compromise, the GIRA 104000 two-channel actuator delivers 16 A per channel in a slim 2-module DIN rail housing. Unlike bulkier multi-channel units, it keeps cabinet footprint minimal while offering manual override and integrated logic — a practical choice for lighting and load control in residential and commercial projects.

Highlights

• Two independent 16 A switching channels for ohmic, inductive, and capacitive loads
• Manual push-button operation and status feedback for on-site testing
• Integrated logic (AND, OR, XOR, gate) and time functions (delays, staircase light)
• Scene functionality for flexible lighting scenarios
• Bus-powered (21–30 V DC) — no auxiliary supply needed

In daily use

Each channel handles up to 3680 W of resistive load, 1380 VA inductive, or 400 W LED, making it suitable for lighting circuits, socket outlets, and small motors. Screw terminals accept solid or stranded conductors up to 2.5 mm², and the IP20 enclosure is intended for distribution boards. The actuator responds to KNX telegrams and can be configured via ETS; manual buttons allow direct switching even before commissioning.
