Since May 21, 2018, the dimensions and drilling pattern have changed; further information is available in the Industry Online Support. SIRIUS 3RF23 semiconductor relay for switching resistive and inductive loads, e.g., for heaters or valves in a filling system. The devices switch wear-free and silently, making them ideal for noise-sensitive areas such as offices and 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. Additionally, the semiconductor relays can be easily expanded for various applications using the standardized function modules 3RF29 by simply clicking them on. The devices are globally certified, e.g., IEC and UL/CSA. The semiconductor relays are available as 1-phase or 3-phase devices and 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. EAN: 4011209591677.
