SIRIUS Contactors (3RT) Everything made easy: Configuring load-feeder Standard SIRIUS modular components are optimally harmonized with one another and can be easily combined with common accessories. These are benefits that our well-proven modular SIRIUS system can offer you for the simple configuration of load feeders. SIRIUS includes everything that you require for switching, protecting and starting motors and systems. Only seven frame sizes cover the complete power range up to 500HP at 600V. Siemens is continually improving and expanding the modular SIRIUS system in order to cost effectively meet all of the requirements from the field. The individual components distinguish...[ Read More ]
SIRIUS Monitoring Relays In our range of SIRIUS relays, you can find everything that you require when it comes to motor feeders. Simple and easy, from a single source. Whether time or reliable monitoring relays, whether narrow interface relays, plugin relays, low-noise power relays or interface converters – it would be difficult to find a more complete and extensive range of relays. We have a relay for simply every application. And by the way: All SIRIUS relays are especially easy to use – and that is accross all lines. Please take a closer look at our range and see for...[ Read More ]
Click for the Latest LOGO! and SITOP Power Supply Information LOGO! Power SuppliesWith the new LOGO!Power powerpacks, not only 24 Volt power loads profit from the advantages of a stabilized power supply. The compact devices are also available with 5 V, 12 V and 15 V output voltage. Two strengths of current are available for each voltage level. The innovated mini powerpacks now require even less mounting space and offer even more functionality. And all that at the favourable prices they are known for. The primary switching power supplies can be used for a wide variety of applications (e.g., for industrial...[ Read More ]
SIRIUS Pushbuttons & Pilot Lights (3SB3) Modular, proven in the field and suitable for industrial environments Siemens range of SIRIUS 22MM pushbuttons and indicator lights distinguish themselves due to their extremely high degree of functionality – and their very modern, flat design. Another convincing feature is the fact that they are extremely easy to mount. This is because actuator, signaling elements, holder as well as contact blocks and lamp elements can be securely and reliably attached with just a few movements of the hand – and that by just one person. Further, the modular design...[ Read More ]
SIRIUS Relays and Opto-couplers (3TX and 3TG) Coupling relays are primarily used after a digital output. Relay and semiconductor outputs are available for this purpose. Choosing which output is the better suited will depend on the application. Relay couplers are standard for AC signals. SIRIUS interface relays are available in compact sizes, 6.2mm wide up to 36mm wide (Power Relay. Variations: Mechanical Relay Semiconductor Relay or Opto-couplers Power Relays Semiconductors are primarily used for switching DC loads and high switching frequencies. SIRIUS Relays (3RH) The SIRIUS coupling relays to switch motors and auxiliary and control circuits have been especially designed to...[ Read More ]
SIRIUS Interface Converters (3RS17) The SIRIUS 3RS17 line of converters are available as either a single signal or universal signal converter. Some models have an Manual-Automatic (M-A) switch built in to a very compact housing as slim as 6.2 mm wide and only as large as 17.5 mm wide. These converters are primarily used for electrical isolation and conversion of analog signals, but another application is possible over the frequency outputs used, whereby the input signal is converted into a proportional frequency. This allows analog signals to be processed with digital inputs. Standard analog signals (0-10V, 0-20ma, 4-20ma, etc) Frequency...[ Read More ]
A Gentle Approach Is Always Best Nowadays, three-phase motors represent the most favored type of drive concept. Direct starting or star-delta starting is, in many cases, not the best solution. Such methods often result in unpleasant side-effects such as mechanical impacts inside the machine or voltage dips in the power supply system. ...[ Read More ]
8WA1 Terminal Blocks Siemens terminal blocks have been designed to complete their industrial control solutions. There are several styles of blocks available from standard feed-thru blocks, double tier blocks, ground terminals and more. There is also a host of accessories to make you connections easier and more clearly defined. Features: Screw Terminal Technology 18 AWG to 500 MCM Insulated on both sides, which means that no end barriers are required. (except double tier through-type terminals) ...[ Read More ]
Time Relays (3RP1) 3RP1 electronic timing relays are used for all time-delayed switching processes in control, starting, protection and regulating circuits. They are the ideal timer modules for industrial cabinets, switchgear and control manufacturers on account of their sophisticated, well-proven design and their space-saving, compact construction. Time Relays for Front Panel Mounting (7PV) 7PV electronic time relays have been optimized as built in devices for operator panels. In terms of their functions, rated voltage and time ranges, they represent the ideal solution no matter what the application. The...[ Read More ]
SIRIUS Motor Starter Protectors (MSP) - 3RV SIRIUS 3RV MSP's are compact, current-limiting protection device. They ensure safe shutdown in the event of a short-circuit and protect loads and plants against overload. Furthermore, they are also suitable for manually switching loads under field conditions and safely isolating the equipment from the main power...[ Read More ]
SIRIUS Overload RelaysSIRIUS overload relays are available in a thermal version and also in a solid-state version for higher requirements. They have the function of providing current-dependent overload protection for loads (e.g.motors) in the main circuit as well as the other switching and protective devices in the load feeder. SIRIUS overload relays can be used to configure compact load feeders and that quite simply and in a space-saving fashion. This is because the overload relays are optimally harmonised to the other components (contactors, soft starters etc.) of the modular SIRIUS system - electrically, mechanically and as visually.The modular SIRIUS system also...[ Read More ]
NEW, ..Three Phase Solid State Contactors for Motor Loads - 3RF24 The new SIRIUS 3-phase solid-state contactors are, for example, used in conveyor technology applications for the switching and reversing of parcel conveyor belts or palleting machines. Also these devices offer a quiet switching behavior and are therefore suitable for all noise-sensitive applications. ...[ Read More ]
