theben BMG 6 T KNX 6-Way Binary Input MIX2 Base Module (SKU 4930230)

Description

Introduction

The theben BMG 6 T KNX (SKU 4930230) is a high-performance 6-way binary input MIX2 base module designed for commercial and high-end residential KNX building automation networks. Operating on standard KNX bus voltage with a minimal bus current consumption of ≤4 mA, this unit acts as a reliable interface for capturing switch and contact signals across building management systems. This device is part of our KNX automation components range.

Engineered for modular flexibility, the BMG 6 T KNX serves as a foundational base module that can be expanded to manage up to 18 channels using compatible MIX2 extension units. Housed in a 4-module wide DIN rail enclosure with IP20 protection and an integrated standby power consumption of approximately 0.3 W, it delivers long-term operational efficiency and straightforward panel integration.

Key Features

• 6-way binary input base module built on the theben MIX2 architecture.
• Expandable channel capacity up to 18 channels using MIX2 extension modules.
• Operates on KNX bus power (≤4 mA) alongside a main supply of 110 V AC to 240 V AC (50 Hz – 60 Hz).
• Compact 4-module width for standard DIN rail installation.
• Integrated auxiliary output supplying 12 V DC at 18 mA (non-SELV).
• Supports solid wire cross-sections from 0.5 mm² to 6 mm² and stranded wire with end sleeves from 0.5 mm² to 4 mm².
• Designed for operating ambient temperatures between -5°C and 45°C with IP20 ingress protection.

Benefits

• Modular Scalability: Designed as a MIX2 base module capable of expanding up to 18 binary channels to meet growing automation requirements.
• Low Energy Consumption: Features an optimized stand-by power consumption of approximately 0.3 W to reduce baseline panel energy draw.
• Flexible Input Voltage Handling: Supports a wide voltage input range from 10 V DC to 240 V AC at 2 mA across connected field contacts.
• Visual Input Status: Equipped with 6 front-facing LEDs that provide clear, real-time status monitoring for each individual input channel.
• SELV Compliance Adaptability: Suitable for SELV applications when all connected inputs are implemented with SELV-compliant signal sources.
