The Interra ITR516-0016 is a 16-channel KNX combo switch actuator delivering 16 A @ 250 V AC per output in a 10-module enclosure (171 × 90 × 64 mm). It is suited to hotel risers, open-plan offices, and large residences that need dense switched and HVAC logic from one DIN device.

Configuration via ETS (S-mode) includes lighting, heating, shutter/blind pairs, fan-coil blocks, scenes, logic gates, timers, and feedback options. The ITR516 variant adds 8 converter objects (versus 4 on 4/8/12-channel models) while retaining the working-hours counter.

Key Features — 16 × 16 A

• 16 × 16 A outputs; 120/165 A inrush per datasheet.
• Output blocks: C1–C6, C7–C12, C13–C18 (partial use on 16-ch device).
• 245 group addresses and assignments; KNX bus max 20 mA.
• Manual override and last-state memory.

Applications and KNX Integration

• Hotel / office cores: Multiple rooms per module with fan-coil and blind logic.
• 12-channel alternative: ITR512-0016 when 12 circuits suffice.
• 20/24 channels: ITR520-0016 or ITR524-0016 (15-module width).

Choosing Interra Combo Actuators

ITR516-0016 maximises outputs in the 171 mm footprint. For smaller cabinets, use ITR508 or ITR512; for 20+ outputs, step to the 15-module models.
