The Interra ITR512-0016 is a 12-channel KNX combo switch actuator with 16 A @ 250 V AC per output. It consolidates lighting, heating, shutter, and fan-coil control for larger apartments, hotel floors, or commercial zones in a 10-module DIN package (171 × 90 × 64 mm).

KNX bus-powered (max 20 mA), S-mode, ETS-configured, with manual override, 245 group addresses, scenes, logic, timers, working-hours counter, and last-state memory — per the ITR5XX-0016 family specification.

Key Features — 12 × 16 A

• 12 relay outputs with 120/165 A inrush capability per channel.
• Two six-output blocks (C1–C6, C7–C12) for structured shutter/HVAC allocation.
• 4 converters, 4 logic gates, working-hours counter (ITR512 row in family table).
• IP 20; −10 °C to +70 °C operating range.
