Siemens SIRIUS 3RF21 solid-state relay for switching resistive/inductive loads, e. g. of heaters or valves in a bottling plant. These devices are non- wearing and silent and are therefore ideal for noise-sensitive areas (offices, hospitals). They are also extremely reliable at high switching frequencies. The compact design saves space on the cooling surface. The solid-state relays can also be expanded for a wide range of applications by simply clicking on the standardized 3RF29 function modules. These devices are approved for worldwide use (e. g. IEC and UL/CSA)
