Description
Introduction
The theben HM 6 T KNX (Item no. 4940240) is a professional 6-way heating actuator engineered for precise heating and cooling regulation within KNX building automation systems. Designed as a FIX1 4-module DIN rail device, it incorporates 6 individual P/PI temperature controllers, allowing direct and efficient control of electrothermal actuators. This device is part of our KNX AC Controller products range.
Operating on an input range of 110 V AC to 240 V AC and output range of 24 V AC to 240 V AC, this unit manages thermal actuators in 2 distinct groups with 3 outputs each. With a low stand-by consumption of approximately 0.5 W and support for multi-phase switching, it serves as a highly dependable component for integrators, panel builders, and HVAC consultants.
Key Features
- 6 triac output channels rated at 0.45 A (450 mA) each.
- Dual group structure organizing 6 outputs into 2 groups of 3 outputs.
- Operating voltage from 110 V AC to 240 V AC at 50-60 Hz, with KNX bus consumption ≤4 mA.
- Protection Class II rated in compliance with EN 60 669 standard.
- Screw terminal connections supporting up to 6 mm² solid wire and 4 mm² stranded wire.
Benefits
- Integrated P/PI controllers provide accurate 6-channel climate control for heating and cooling systems.
- Wide output voltage support ranging from 24 V AC to 240 V AC accommodates various thermal drives.
- Low standby power consumption of ~0.5 W minimizes ongoing operational energy costs.
- Compact 4-module width design saves valuable space in electrical distribution boards.
- Flexible switching capability allows for multi-phase operations and SELV compliance when configured uniformly.
