The diagnostic functions of the new switching actuators make it possible to continuously monitor the functions of the switching actuator or to initiate maintenance based on operating hours or number of switching cycles.
With their many automation functions, the new switching actuators are particularly suitable for offices, hotels and schools as well as for industrial environments and retail stores. The actuators can switch incandescent lamps as well as electric heaters (resistive loads), low-voltage halogen lamps with upstream wound transformers and electric motors (inductive loads) as well as low-voltage halogen lamps with upstream electronic transformers (capacitive loads). Thanks to their high switching capacity, the actuators can also be used in parking lot and outdoor lighting. With their greater flexibility, the new GAMMA instabus switching actuators make it possible to implement individual system solutions, thus creating perfect places.
Shorter installation time and simplified commissioning
Maintenance-free plug-type terminals significantly shorten the installation time for the new switching actuators. The annual maintenance and tightening required for screw-type terminals is eliminated. The terminals are designed for connection and through-wiring of single-core, stranded and multi-core conductors with a conductor cross section of 0.5 to 2.5 mm². Stranded and multi-core conductors can be plugged into the terminals without ferrules.
Slide switches and special test contacts on the plug-type terminals enable electrical installers to test the installation entirely electrically, using common test equipment such as a voltage detector. This makes it possible to document the flawless execution of the installation work when handing the project over to the system integrator. Electrical installers, system integrators and planners thus have clearly assigned responsibilities within the construction process, which becomes much more efficient overall.
The switching actuators are based on the KNX standard and can be flexibly networked with all components of KNX building services and building systems. The actuators are designed for a rated operating voltage of 230 volts AC and protection class IP20. The actuators' electronic components are supplied from the KNX bus voltage. The new switching actuators are suitable as DIN rail-mounted devices for installation in distribution cabinets or small housings and can be snapped onto 35 mm rails according to EN 60715-TH35.
