Weinzierl KNX IO 510.1 Switching Actuator 5444 with 2 Outputs, Logic and Timer Functions

In KNX installations, controlling multiple loads with advanced logic and timing often requires separate modules and complex programming. The Weinzierl KNX IO 510.1 Switching Actuator 5444 solves this by integrating two powerful relay outputs with eight independent logic gates and eight timer functions in a compact 2-unit DIN rail device.

Who is it for

This actuator is intended for KNX system integrators and electricians who need reliable switching of lighting, heating, or other electrical loads with the flexibility of on-board logic and timing, without additional hardware.

Main features

• Two potential-free relay outputs, each rated for 16 A at 250 V AC resistive load.
• Eight independent logic gates (AND, OR, XOR, NAND, NOR, XNOR) for combining KNX group objects.
• Eight independent timer functions (delay, pulse, staircase light) for time-based control.
• Per-channel functions: switching, scene control, status feedback, central control, and forced operation.
• Powered directly from the KNX bus (21–30 V DC), consuming only 10 mA.
• Compact DIN rail mounting, occupying only 2 units (36 mm).
• Integrated short-circuit and overload protection for device safety.
• High mechanical endurance of over 1,000,000 switching cycles and electrical endurance of over 100,000 cycles at rated load.

Tips

Use the integrated logic gates to create complex control scenarios without additional logic modules. The timer functions are ideal for staircase lighting or delayed switch-off. Ensure the DIN rail location is within the operating temperature range for reliable performance.
