Modular components for control and signaling devices. Up to modules can be connected side by side and, for contact modules, stacked behind each other. Available either as a contact module in screw-spring technology with normally open/normally closed contacts or as an LED module with various colors and voltages. Under the brand name SIRIUS ACT, Siemens offers a unique portfolio of control and signaling devices with global product approvals in four modern design series made of robust real metal and high-quality plastic. The innovative snap-on concept simplifies assembly to the extent that only one hand and no special tools are required. For mounting holes, non-threaded holes are sufficient, as a 100% anti-rotation protection is already integrated. Thanks to the consistently high protection class, the robust devices are suitable for industrial use and outdoor applications. Even cleaning with a high-pressure jet is possible. Neither dust, oils, nor aggressive alkalis can disrupt reliable operation. In addition to standard wiring, the devices can also be connected to the control system via PROFINET, AS-Interface, or IO-Link. This reduces your wiring effort, minimizes sources of error, and provides greater flexibility. The graphical online configurator conveniently assists in selecting and ordering individual devices, enclosures, and labels. Extensive documentation, such as manuals, 3D data, and connection diagrams, is available. SIRIUS ACT Performance in Action for commanding and signaling. Easily assembled, simply strong, simply perfect.
