Solid-State Switching Devices for Resistive Loads 3RF29 Function Modules General data ■ Overview Function modules for SIRIUS 3RF2 solid-state switching devices The following function modules are available: • Converters • Load monitoring • Heating current monitoring • Power controllers • Power regulators A great variety of applications demand an expanded range of functionality. With our function modules, these requirements can be met really easily. The modules are mounted simply by cli- cking them into place; straight away the necessary connections are made with the solid-state relay or contactor. The plug-in con- nection to control the solid-state switching devices can simply remain in use.
With the exception of the converter, the function modules can be used only with single-phase solid-state switching devices. ■ Technical specifications 1) Note limitations for power controller function modules. These modules were built as Class A devices. The use of these devices in residential areas could result in lead in radio interference. In this case these may be required to introduce additional interference suppression measures. 44 Siemens · 2009 Type 3RF29 ..-.E... 3RF29 ..-.F... 3RF29 ..-.G... 3RF29 ..-.H... 3RF29 ..-.J... 3RF29 ..-.K...
