The Interra ITR104-0010 is a 4-channel KNX binary interface that bridges conventional switches and dry contacts into KNX automation. It is designed for installations where more input points are needed per location than a 2-channel interface can provide.

Using ETS5 or higher, each channel can be configured independently for switching, dimming, shutters, scenes, RGB/RGBW control, and sequencing logic. Dual-input operating modes are supported where required (for example, two-button dimming and shutters/blinds).

Key Features — 4-Channel Universal Interface

• 4 binary input channels for conventional controls.
• ETS-based mapping with independent per-channel assignment.
• Extended KNX functions including scenes and RGB/RGBW objects.
• Two-input modes for dimming and blinds.

Applications and KNX Integration

• Mid-density retrofit: Four inputs from one compact module.
• Panel simplification: Fewer modules versus multiple 2-channel units.
• Related modules: ITR102-0010 (2 ch), ITR108-0010 (8 ch).

Choosing Interra Input Modules

Select ITR104-0010 when 4 dry-contact channels are required per node. For analog temperature and thermostat features, choose ITR106-0011.
