The HDL-M/R16.10.1 KNX 16CH 10A High Power Switch Actuator is a high-density DIN-rail relay module for switching up to sixteen independent 10 A lighting circuits. Each channel handles a rated 10 A lighting load with maximum inrush current of 500 A, making it suitable for commercial and large residential projects where many switched loads must be consolidated in one distribution board.

Part of HDL's 10 A high-power switch actuator family (also available in 4CH, 8CH, and 12CH variants), the M/R16.10.1 offers advanced KNX logic functions — including AND, OR, XOR, and Gate — alongside staircase, scene, threshold, and curtain control. The series supports three-phase mains connection for balanced load distribution across L1, L2, and L3.

Applications and KNX Integration

• Commercial lighting: Switch sixteen lighting circuits from KNX presence detectors, schedules, and touch panels.
• Curtain and HVAC: Curtain control and PWM heating output per channel for integrated room automation.
• Logic-heavy projects: Built-in AND/OR/XOR/Gate functions reduce external logic modules.
• Dimming alternative: For phase-dimmable loads, use the HDL-M/DM06.1 6CH MOSFET Dimming Actuator or M/DM04.1 4CH Dimming Actuator.
• DALI installations: For DALI luminaire control, use the HDL M/DALI.1 KNX DALI Gateway.
• System power: Supply the KNX bus from an HDL M/P960.1 960 mA Power Supply.

Choosing HDL Switch Actuators

The M/R16.10.1 is the highest-density 10 A switch actuator in the HDL range — sixteen channels in one 216 mm module. For smaller panels, HDL offers M/R4.10.1, M/R8.10.1, and M/R12.10.1 variants with the same 10 A per-channel rating and logic feature set.
