Revolutionize commanding & signaling, discover SIRIUS ACT push buttons
Highlights at a glance
SIRIUS ACT is a modular system of push buttons and indicator lights for front plate mounting and rear-mounted electrical modules. It can be flexibly configured to specific customer requirements and features extensive accessories. For common applications, complete devices are offered.Maximum flexibility thanks to a variety of communication solutions
Communication is one of the strong points of SIRIUS ACT. In addition to the conventional screw and spring-type connections of the command and signaling devices, direct connections to PROFINET can also be implemented in the control cabinet or IO-Link and AS-Interface in the field.
The various communication interfacing options provided enable simple combinations of push buttons and signaling devices, HMI touch screens and industrial PCs, which means that complex input stations can be set up without extensive wiring and engineering time and effort.
Integration into the TIA Portal enables them to be visually displayed for better harmonization with the hardware, thus simplifying and speeding up hardware configuration. Further advantages are uniform data management, time savings thanks to intuitive hardware configuration and lower downtimes resulting from faster fault diagnostics. The option handling feature (especially with PROFINET) enables flexible systems to be designed and individually adapted – even during ongoing operation.
The new direct connection of SIRIUS ACT to PROFINET/PROFIsafe
The quick and easy installation with ribbon cable (piercing technology) without special tools saves considerable wiring effort.
- Reduced wiring and fewer error sources at installation and commissioning
- High flexibility for modifications due to the modular plug-in design
- Extended diagnostics and parameterization options resulting from integration in the TIA Portal
- Safety Integrated: EMERGENCY STOP incorporated via PROFIsafe

Use of electrical equipment in gas/dust atmospheres
SIRIUS ACT pushbuttons and indicator lights are suitable for use in intrinsically safe circuits, in accordance with the requirements of IEC 60079-11:2011, Clause 5.7 Simple apparatus. For the illuminated SIRIUS ACT versions, the ATEX-certified intrinsically safe LEDs must be used.

The LED modules of type 3SU1401-*BB*0-*AA2 are approved in accordance with IEC EN 60079-11:2012 (Equipment protection by intrinsic safety "i") and are used in gas hazardous zones 1 and 2. They comply with the "ib" type of protection for intrinsic safety. They may only be used in connection with a 3SU1 pushbutton or indicator light, in the enclosure or a control panel. The use of standard (non-ATEX) LED modules in intrinsically safe circuits is not permitted.

The SIRIUS ACT configurator offers you many advantages. Enclosures and labeling can be combined individually and to suit specific customer needs – and this is done particularly easily thanks to graphics-based component selection with a drag-and-drop function and a graphical preview. Using the automatically generated CIN number, you can order your enclosure configuration at any time again without the need to enter any more data.
