5WG1536-1DB31 N 536D31 KNX 4-Channel Switch/Dim Actuator 4x230V 10AX 1-10V DIN Rail

The N 536D31 (5WG1536-1DB31) provides KNX installations with direct control of luminaires dimmed through 1-10 V control inputs. Each channel features two integrated terminals: a 230 V switching contact for physical lamp circuit isolation and a passive DC 1-10 V output for controlling ECG or LED driver brightness. With four channels packed into a six-module rail device, this unit is ideal for distribution boards in buildings with existing fluorescent or dimmable LED lighting systems.

• Protocol & Bus Data: KNX device with 24V DC bus supply (21-30V DC); 20 mA bus current, 0.24 W internal power loss; compatible with KNX PL-Link
• Outputs: 4 potential-free bistable relay contacts plus 4 passive DC 1-10 V control outputs (channels A, B, C, D)
• Switching Capacity: 230V AC rated contact voltage; 16A resistive loads, 10AX lamp loads; 3680W per output
• Dimming Interface: Maximum 106 mA per control output; supports up to 53 ECGs/LED drivers; control line length up to 100m
• Mechanical: DIN rail mounted (6 TE/108mm width); 279g weight; IP20 rating; -5 to +45°C operating temperature
• Reliability: 1,000,000 mechanical cycles; 100,000 electrical cycles; configured with ETS 4.2+

Ideal for floor distribution boards supplying dimmable fluorescent or LED lighting in offices, hotels, schools, and industrial facilities. Particularly suited for applications requiring individual zone mains isolation for maintenance with common 1-10 V dimming control. The mixed capability of dimming and switching channels (16A resistive rating) makes it versatile for complex distribution boards. Building-site operation and override blocks facilitate phased handover in large projects.
