© Siemens AG 2010 Soft Starters and Solid-State Switching Devices General data Ideal for operation with heating control systems Also for switching motors The 3RF2 solid-state switching devices can be used for example in the SIPLUS HCS300I heating control system. They are opti- mally connected to the digital output module of the HCS300I by means of preassembled cables. This saves considerable wiring outlay in the control circuit and shortens mounting time. In order to achieve higher productivity, the switching frequency is continuously increased. It is no problem for our SIRIUS solid- state contactors to switch motors.
With induction motors up to 7.5 kW, they can reliably withstand even the highest switching frequencies. Even a continuous change in the direction of rota- tion is possible with the solid-state reversing contactors. Both versions can be perfectly combined with components from the SIRIUS modular system. Connecting with SIRIUS motor starter protectors or SIRIUS overload relay can be implemented without any further steps. Always on the sunny side with SIRIUS Because SIRIUS 3RF2 offers even more: • The space-saving and compact side-by-side mounting ensure reliable operation up to an ambient temperature of +60 °C.
• Thanks to fast configuration and the ease of mounting and start-up, you save not only time but also expenses. Connection methods 4 The devices are available with screw terminals (box terminals), spring-type terminals or ring terminal lugs. Screw terminals The HCS300I is a modular heating control system for the optimi- zation of plastic processing machines. It enables individual so- lutions for many different heating control applications. With each basic unit it is possible to use up to four 6-channel digital outputs to control solid-state switching devices and four 4-channel tem- perature measuring modules. Current or current-and-voltage measuring modules can be used to monitor the loads.
Commu- nication with the higher-level control system is through Profibus DP. Spring-type terminals Ring terminal lug connections The terminals are indicated in the selection and or- dering data by orange backgrounds.
