The Interra ITR500-0001 is a 6-channel KNX ballast / 0–10 V dimming module for electronic ballasts and drivers with a 0/1–10 V (Interra page also notes 2–10 V) control interface. Each channel combines a 0–10 V DC dimming output (24 mA per channel) with a switched load path rated 10 A @ 220–250 V AC. Manual buttons allow local on/off and dimming; both absorbing and output-type ballasts can be connected. Commissioning is ETS (S-Mode) only.

Typical lighting functions listed by Interra include status response/recovery, upper/lower limits, staircase lighting, scene control and scene dimming, sequence control, threshold switching, statistical total ON time, and heating-actuator (PWM) use cases. Protect each switched circuit with a 10 A fuse/breaker and keep KNX wiring separated from AC power.

Key Features — 6 × 0–10 V + 10 A

• 6 independent channels: Analogue dimming plus switched output per channel.
• 0–10 V control: 24 mA @ 0–10 V DC per channel (Interra datasheet).
• 10 A switching: Max. 10 A @ 220–250 V AC (50/60 Hz) per channel.
• Manual operation: Front buttons for switching/dimming without ETS online.
• Scenes & staircase: Scene dimming, sequences, limits and staircase light in the application.
• MDRC: 90 × 144 × 66 mm; bus-powered 10 mA; IP20; KNX certified.

Applications and Related Products

• Analogue ballast lighting: Offices and hospitality where 0/1–10 V ECGs are used instead of DALI.
• 4-channel sister: ITR500-0003 (4 × 0/1–10 V, 16 A relays).
• DALI alternative: ITR832-0001 / ITR832-0011 when the project standardises on DALI-2.
• Bus power: Allow for 10 mA (e.g. ITR900 640 mA).

Choosing and Commissioning

Choose ITR500-0001 for six analogue ballast channels with 10 A switching. Fuse each load circuit at 10 A; do not inject 230 V onto the KNX bus. Program only with ETS. Full ratings, wiring and function lists are in the Datasheet and Product Manual under Downloads.
