MDT Universal Actor AKU-0616.03 6-fold relay output 16A 230VAC

MDT Universal Actor AKU-0616.03 6-fold relay output 16A 230VAC is a compact DIN-rail module for building automation that provides six independent relay channels for switching AC loads up to 16 A per channel. Designed for integration into KNX and other automation systems, this actor enables centralized control of lighting, small motors, heating actuators and other 230 VAC appliances while conserving installation space and simplifying wiring.

Advantages

The device combines six galvanically isolated relay outputs in a single housing, offering robust switching capability for resistive and inductive loads at 230 VAC. Its DIN-rail form factor and standardized electrical connections reduce installation time and allow neat cabinet layouts. Reliable mechanical relays provide predictable behaviour for both manual and automated control scenarios, while compatibility with common automation buses ensures seamless integration into scenes, timers and logic functions.

Suitable for

• Switching lighting circuits (LED, halogen, fluorescent) up to 16 A per channel
• Controlling small motors and ventilation units
• Integration with KNX or similar home/building automation systems
• Centralized control of sockets and household appliances
• Scene control and energy management installations

Key specifications

• Number of relay outputs: 6 channels
• Maximum switching current per channel: 16 A (at 230 VAC)
• Rated voltage: 230 VAC switching capability
• Output type: mechanical relay contacts (galvanically isolated)
• Mounting: DIN-rail mount
• Typical application: lighting, motor loads, household appliances

How to use

Mount the module on a standard DIN rail inside the switchboard and connect supply and load conductors according to local electrical codes. Integrate the actor with the building automation bus or control interface following the system’s commissioning procedure. Assign outputs to the required group addresses or logical functions, then test each channel with the intended loads to verify correct switching and protective device coordination. Ensure that protective devices (fuses, circuit breakers, RCDs) are selected to match the connected load and local regulations.

Usage recommendations

Use the MDT actor to centralize switching points where multiple independent 230 VAC circuits are required. Avoid exceeding the 16 A rating per channel and consider inrush currents for motors and certain lamp types when sizing protective devices. For extended reliability, follow recommended installation practices, keep wiring lengths and contact loads within manufacturer guidelines, and schedule periodic functional checks as part of building maintenance.
