SAH/S8.6.7.1 KNX Switch/Shutter Actuator: 8-fold, 6 A Combi Actuator
The outputs can be used in two primary modes: individually for switching electrical loads (up to 8 channels) or in pairs to control 230 V AC roller shutter or blind drives (up to 4 channels). A key operational feature is the manual operation capability, which allows for local control and displays the switching or driving status, and can be disabled if required.
Notably, the SAH/S8.6.7.1 is entirely powered by the KNX bus and requires no auxiliary power supply, simplifying wiring and installation.
1. SAH/S8.6.7.1 KNX Switch/Shutter Actuator: Dual Functionality and Reliability
Combining switching and shutter control in a single compact unit for optimal panel efficiency.
Operational Flexibility:
- Channel Count: Features 8 independent outputs (relays).
- Combi Function: Outputs can be freely configured: up to 8 switching channels or up to 4 shutter/blind channels (controlling 230 V AC drives).
- Rating: High-capacity switching with a 6 A rated current and a maximum switching power of 1200 W per channel.
- Manual Control: Includes manual operation buttons on the front panel with clear ON/OFF status indication via LEDs, useful for commissioning and troubleshooting.
Installation and Power:
- Power Supply: KNX bus-powered—no external auxiliary voltage is required.
- Installation: Designed for DIN-Rail mounting, occupying 4 modular spacings (70 mm width).
- Power Loss: Low power loss of 2.5 W.
2. Technical Details and System Integration
This actuator is a central control component for both lighting and shading applications.
- Voltage Range: Switching voltage is 230 V AC.
- Control Input: Typically controlled by a KNX Push-button or a KNX Universal Interface (Internal Links).
