theben RM 16 T KNX Switch/Blind Actuator (4940205)

Description

Introduction

The theben RM 16 T KNX (Item no. 4940205) is a versatile DIN rail actuator designed for modern KNX building control systems. Part of the FIX2 series, this device provides flexible channel selection, functioning either as a 16-way switching actuator or as an 8-way blind actuator to control motor drives efficiently across commercial and residential installations. This device is part of our KNX automation components range.

Operating on a KNX bus voltage with a current consumption of less than 4 mA, the actuator manages operating voltages from 110 V AC to 240 V AC at 50 to 60 Hz. Each channel is equipped with an LED switching status display, providing clear local visual feedback during commissioning and routine operation.

Key Features

• FIX2 series flexible channel function selection for switching or drive control.
• 16 configurable channels (16 switching outputs or 8 blind drive channels).
• LED switching status display dedicated to each channel.
• Handles peak inrush current up to max. 800 A / 200 µs.
• Low bus current consumption of under 4 mA.
• Supports solid wire cross-sections from 0.5 mm² to 6 mm² and stranded wire with end sleeve from 0.5 mm² to 4 mm².
• DIN rail mounting format for standard distribution panel installation.

Benefits

• Flexible Channel Configuration: Offers versatile configuration as a 16-channel switching actuator or an 8-channel actuator for blind and shutter drives.
• High Inrush Current Resistance: Supports high peak inrush currents up to max. 800 A / 200 µs for demanding load conditions.
• Low Standby Consumption: Optimizes energy efficiency with a stand-by power consumption of approximately 0.5 W.
• Clear Visual Feedback: Integrated LED switching status display for each channel allows immediate status verification.
• Wide Load Support: Rated to handle various electrical lighting loads including LED lamps, fluorescent lamps, energy-saving lamps, and incandescent or halogen lighting.
