Rethinking Panel-mounted Push Buttons & Signaling DevicesBy Bill Lydon, Editor
This year Siemens launched a new line of panel controls and indicators named the SIRIUS ACT. Curious as to why Siemens would make such a significant investment to redesign a mundane, very traditional product, I contacted JuergenDuemmler, Product Marketing Manager,DigitalFactoryControls Products, to learn more.
The Sirius Act mounting system is designed for faster and more efficient installation of devices like selector switches, keyed switches, and potentiometers. The screwed clamping method incorporates a twist prevention design to ensure reliable installation, eliminating the requirement for keyed/notched holes.This is accomplished by inserting devices through the panel hole and snapping it into a holder located on the inside the panel. It is secured by tightening a screw of a clever new clamping design. The holder base accepts modules for panel device functions including communications options. The front of the holder features a range of actuators and indicators, while the rear holder has slots to accept contact and LED modules. There is sufficient space to accommodate up to three modules side by side and two contact modules, one behind the other. The modules are available with screw terminals, spring-type terminals or solder pin connections.
Siemens currently offers a front plate mounted SIRIUS ACT series EMERGENCY STOP device with an AS-Interface option to the AS-Interface bus system according to ISO 13850. The plan is to expand the line of panel devices that plug into SIRIUS ACT components to support AS-Interfaceand IO-Linkfor simplify panel wiring. Duemmler noted that PROFINET will be available in the future.
Sirius Act devices are installed without the need for notches with a new mounting design. Devices are secured using a screwdriver.
Holder base grabs the cabinet with 8 anti-rotation spikes and has a grounding spike (at the top) which penetrates the enclosure or panel.
The Sirius Act line of commanding and signaling devices, which meet IP69K specifications when properly installed, are appropriate for potentially explosive atmospheres and is unaffected by dust, oils, caustic solutions and extreme environmental influences. Sirius Act can safely be cleaned with a high-pressure waterjet at high-temperatures.
Siemens provides an online configurator for efficient application engineering and ordering. Single devices, housings and inscriptions are defined online to meet customer requirements. An automatically generated customer-specific configuration CIN order reference number enables customers to reorder their configuration at any time without having to provide any further details. The online configurator provides download options for documentation, exploded views and connection diagram.
Thoughts & Observations
Major shifts in technology get the headlines but there are many ways to improve productivity, function, and effectiveness. SIRIUS ACT is a great example of using innovation to improve essential control components.
Industrial networks are starting to be added to panel components. Users benefit from direct data linkages to automation systems because of simplified installation; plus more information can be fed into control and automation systems.
