MDT AMS-0416.03 KNX attuatore di commutazione 4 canali, 16 A, 4 TE guida DIN

Managing multiple lighting or load circuits in a KNX installation often requires separate actuators, increasing wiring complexity and panel space. The MDT AMS-0416.03 solves this by integrating four independent switching channels in a compact 4 TE DIN rail module, each rated for 16 A at 230 V AC.

Who is it for

KNX system integrators and electricians who need reliable, high-current switching for lighting, heating, or other resistive loads in residential and commercial buildings, with the convenience of manual operation per channel.

Main features

• Four potential-free normally open contacts, each switching up to 16 A ohmic load at 230 V AC.
• Manual switching per channel for testing and commissioning without bus power.
• Integrated KNX bus coupler with screw terminals for secure wiring.
• Supports scene control, logic functions, hour meter, staircase light function, central functions, and status feedback.
• Compact 4 TE (72 mm) width for efficient use of distribution board space.
• Firmware update possible via ETS (ETS 4.2 or higher required).

Tips

For inductive loads such as motors or fluorescent lamps, derate the switching current and consider using an external contactor. Always install an appropriate external fuse per channel to protect against short circuits. Use the manual operation feature to verify wiring before commissioning the KNX system.
