Siemens Digital Industries Semiconductor Relay 3RF2320-1DA44: additional details
1-phase semiconductor relay 3RF2 AC 51 / 20 A / 40 °C 48-460 V / DC 4-30 V short-circuit proof with B-automatic. SIRIUS 3RF23 semiconductor relay for switching resistive/inductive loads, e.g., for heaters or valves in a filling plant. The devices switch wear-free and silently, making them ideal for noise-sensitive areas (offices, hospitals). They are also extremely reliable at high switching frequencies. With the heat sink already integrated, they can be directly installed in the control cabinet. The compact design saves space on the DIN rail. The semiconductor relays can also be easily expanded for various applications by simply clicking on the standardized function modules 3RF29. The devices are globally approved (e.g., IEC and UL/CSA). The semiconductor relays are available as 1-phase or 3-phase devices. They come in various power ratings and rated operating voltages. Designed for AC or DC actuation, they are available with screw, spring-loaded, or ring terminal connections. Accessories include not only the function modules 3RF29 but also control plugs and terminal covers. Simple, efficient, always up to date - the SIRIUS system modular concept.
