N 536D51 5WG1536-1DB51 KNX Switch Dim Actuator 8 Gang 230V 10AX 1-10V Outputs Rail 8TE

The N 536D51 extends the 1-10V switching/dimming concept to eight channels, providing high-density control for multiple lighting groups. Each channel combines a mains contact for lamp circuit isolation with an analogue output for brightness control, all packed into eight module widths with shared front keypad and LED indicators for local monitoring.
