N 141/31 5WG1141-1AB31 KNX DALI Gateway Twin 2 Lines 128 Ballasts 32 Groups Stand Alone
The N141/31 is the basic twin model in the KNX/DALI family, serving as an entry point for projects requiring two DALI lines at moderate cost. This gateway efficiently brings large numbers of digital ballasts under KNX control, organizes them into groups, drives them through scenes, and maintains lighting operation when the automation network is unavailable.
| Protocol & Addressing | KNX TP1 device with two DALI interfaces to IEC 60929 Each interface supports up to 64 DALI ballasts Maximum 128 ballasts across both lines Up to 32 DALI groups Status and lamp-failure feedback per group and device |
|---|---|
| Power Supply | 110-240 V AC, 50/60 Hz or 120-240 V DC DALI bus voltage: maximum 19 V, short-circuit proof Powers connected DALI sensors Additional DALI supply not required or permitted |
| Local Interface | LC display for operating mode and error text One key toggles between bus and direct mode Two keys for switching all ballasts on/off Individual status LED for each DALI output |
| Functions & Operation | Broadcast operation for entire lines Group control with switching and dimming 16 two-level controllers for brightness-dependent switching Timer functions (one- or two-level) 32 scene control capability Stand-alone operation during KNX communication failure |
| Engineering & Mechanical | ETS plug-in with table-oriented parameter view Customizable columns with sorting and filtering Configuration stored in ETS project Import function for data from other KNX/DALI gateways Requires ETS 5 or above with firmware V15 4 module widths (72 mm) on DIN rail EN 60715-TH35-7.5 Weight: approximately 0.47 kg |
Compared to plus models, this device omits:
- DALI sensor and input-device support
- Emergency lighting test logging
- Constant-light and two-point control
- Timer/effect blocks and pre-loaded applications
Broadcast, group, scene, and stand-alone operation remain fully available.
DALI-2 certificate valid where DALI-2 logo appears on device label.
Ideal for office buildings, hotels, shopping centers, airports, and campus buildings where luminaires require individual addressing but primarily group control. The 32 groups effectively separate work zones in planning offices and multipurpose halls. The autonomous operation capability makes it suitable for areas where lighting must remain operational during KNX network maintenance.
