Actuator Steinel Universal Actuator STEINEL True Presence KNX UA16 KNX-S 16A

The Actuator Steinel Universal Actuator STEINEL True Presence KNX UA16 KNX-S 16A is a KNX-compatible switching actuator designed for integration into building automation systems. It provides centralized control of electrical loads and supports automated presence-based operation for lighting and other circuits. The device is intended to reliably switch resistive and inductive loads up to 16 A and to interface with KNX bus systems for coordinated control within smart building installations.

Advantages

This KNX switching actuator offers compact integration into electrical distribution boards and predictable switching behavior for a range of loads. It supports presence-driven logic and centralized control through the KNX bus, enabling coordinated operation with sensors, timers and other KNX devices. The actuator is engineered for long-term reliable switching of lighting circuits and other electrical consumers, reducing the need for separate relays or mechanical switches in automated installations.

Suitable for

• Switching lighting circuits in residential and commercial KNX installations
• Controlling small motors, transformers and inductive loads within the specified current rating
• Integration with presence sensors and timed scenes for energy-efficient automation
• Centralized control of distribution circuits in building management systems

Key specifications

• Compatibility: KNX bus system for building automation communication
• Switching capacity: up to 16 A per channel for resistive and inductive loads
• Function: switching actuator for on/off control of connected circuits
• Mounting: designed for installation in electrical distribution panels or DIN rail environments
• Control interfaces: integrates with KNX group objects and supports standard KNX commands

How to use

Install the actuator in the distribution board or DIN rail space according to local electrical regulations and wiring standards. Connect the actuator to the KNX bus and assign group addresses for the loads to be controlled. Wire the output channels to the respective lighting or electrical circuits ensuring the total connected current does not exceed the 16 A rating per channel. Configure switching logic, presence-based behavior and scenes via the KNX commissioning tool. After commissioning, use KNX switches, presence sensors or automation logic to operate the connected loads.

Usage recommendations

Verify load types and inrush currents prior to installation to ensure compatibility with the actuator's 16 A switching capacity. Use proper circuit protection and adhere to local installation codes. For mixed loads or high inrush devices, consider appropriate derating or use of external contactors to protect the actuator and extend service life.
