theben JMG 4 T KNX 4-Way Blind Actuator MIX2 Base Module (4930250)

Description

Introduction

The theben JMG 4 T KNX (Item no. 4930250) is a high-performance 4-way blind actuator designed for DIN rail mounting in KNX building automation systems. Built as a MIX2 base module, this device offers modular channel expansion, allowing system integrators to scale up to a maximum of 12 channels by connecting additional MIX2 extension units. This device is part of our KNX automation components range.

Engineered for high efficiency and reliability, the unit operates on a wide mains supply voltage of 110 V AC to 240 V AC at 50 Hz to 60 Hz while consuming approximately 0.3 W in stand-by mode. Featuring potential-free 6 A normally open (NO) contacts, it provides precise and dependable control for motor-driven blinds and shading installations.

Key Features

• 4-channel blind actuator base module belonging to the theben MIX2 series.
• Powered via KNX bus voltage with low current draw (<4 mA).
• Terminal screw connections for main power and dedicated KNX bus terminal.
• Flexible wiring support for solid wire (0.5 mm² to 6 mm²) and stranded wire with sleeve (0.5 mm² to 4 mm²).
• Protection class II compliant according to EN 60 669 with an IP 20 ingress protection rating.
• Designed for standard ambient operating temperatures ranging from -5°C to 45°C.

Benefits

• Modular MIX2 base module structure enables effortless channel expansion up to 12 channels.
• Energy-efficient performance with a low stand-by power consumption of approximately 0.3 W.
• Versatile mains operating range supporting 110 V AC to 240 V AC at 50–60 Hz.
• Robust switching capacity with potential-free 6 A NO contacts for motor control.
• Compact 4-module width design suitable for standard DIN rail distribution panels.
