5WG12621DB31 N262D31 KNX Binary Input 4 Ch Potential Free Alu Silver

The 5WG12621DB31 (N 262 D31) is a KNX binary input module providing four potential-free (dry contact) input channels for integrating conventional volt-free contacts into a KNX building automation system. Each channel independently processes signals from push buttons, window/door contacts, motion detector relays, or any potential-free switch, converting them to KNX bus telegrams.

DIN-rail mountable in standard distribution panels, the aluminum silver-coloured (D31) housing is robust and suitable for electrical cabinet installation. Programmable via ETS with flexible per-channel function mapping for switching, dimming, shutter, or value sending.

Application Scenarios

The N 262 D31 is suited for DIN-rail installation in electrical distribution panels alongside other KNX actuators and power supplies. Typical use cases include connecting conventional push buttons, rocker switches, magnetic door contacts, window sensors, or relay outputs from third-party systems directly to the KNX bus.

Each input can be independently configured in ETS for short-press, long-press, or toggle operation
Versatile for lighting control, shutter management, HVAC scene selection, and alarm integration
Widely used in commercial offices, hotel rooms, smart homes, and industrial automation panels
