theben RME 8 S KNX 8-Way Switching Actuator Extension Module (4930225)

Description

Introduction

The theben RME 8 S KNX (Item no. 4930225) is an 8-way switching actuator extension module designed for integration within the MIX2 module system. Mounted on a standard 4-width DIN rail, this extension unit allows system integrators to upgrade and expand automated switching capacity up to a maximum of 24 channels when combined with base modules. This device is part of our KNX system components range.

Built to Protection Class II standards and equipped with standard screw terminals, the module handles a broad range of electrical loads. It supports resistive loads up to 3680 W, uncorrected and parallel-corrected conventional fluorescent lamps, electronic ballast loads, energy-saving lamps, and low-wattage LED lamps.

Key Features

• 8-way switching actuator extension module within the theben MIX2 system.
• Provides 8 independent NO contact channels rated for 16 A and 3 A loads.
• Capable of expanding total system switching to 24 channels.
• Supports resistive loads up to 3680 W.
• Handles parallel-corrected fluorescent lamp loads up to 1300 W (140 µF) and uncorrected loads up to 2000 VA.
• Supports electronic ballast fluorescent loads up to 1200 W, energy-saving lamps up to 300 W, and LED lamps (< 2 W) up to 55 W.
• DIN rail mounting with screw terminal connections.

Benefits

• Flexible MIX2 System Expansion: Serves as an extension module to scale KNX switching setups up to 24 total channels.
• Broad Lighting Load Compatibility: Efficiently switches conventional, electronic ballast, energy-saving, and LED lamp loads.
• Versatile Terminal Connection: Screw terminals accept solid wire cross-sections up to 6 mm² and stranded wire with end sleeves up to 4 mm².
• Standardized Enclosure: Compact 4-module width form factor for standard DIN rail distribution board installation.
• Certified Electrical Safety: Features Protection Class II design with contact opening width of less than 3 mm.
