theben RME 4 I KNX 4-Way Switching Actuator (4930215)

Description

Introduction

The theben RME 4 I KNX (Item no. 4930215) is a high-performance 4-way C-load switching actuator extension module from the MIX2 series, engineered specifically for controlling demanding switching loads within KNX building automation systems. Operating reliably at 110 V AC to 240 V AC (50 Hz – 60 Hz), this actuator provides robust control for high-capacity lighting and heavy electrical loads. This device is part of our KNX Actuators products range.

Featuring integrated current recognition, the RME 4 I KNX enables real-time load monitoring and fault detection across its 4 independent output channels. With a high peak inrush current tolerance of up to 1500 A for 200 µs, this device is optimized for modern LED drivers, electronic ballasts, and capacitive loads while maintaining an efficient standby consumption of approximately 0 W.

Key Features

• 4 independent switching channels with NO contact design (16 A, 10 A).
• MIX2 series extension module with C-load design and built-in current recognition.
• Operating voltage range of 110 V AC to 240 V AC at 50 Hz to 60 Hz.
• Maximum peak inrush current rating of 1500 A / 200 µs.
