Evaluation unit for full motor protection (monostable) for IO-LINK Size S00...S12,CLASS 5...30 Stand-alone installation Main circuit: -- Auxiliary circuit: Screw connection Manual-automatic RESET Electronic overload relay for IO-Link SIRIUS 3RB24 for advanced applications for current and temperature-dependent protection of consumers with normal and heavy starting against impermissibly high heating. Thanks to particularly large current setting ranges and different tripping characteristics, entire series of motors are covered with just a few types. With their low power loss, they are particularly energy-efficient and contribute to less heating in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive applications (ATEX) are a matter of course. The devices are available with monostable or bistable output relays. Versions with communication via IO-Link are also available. All are available with screw or spring-loaded connections for a quick, maintenance-free and vibration-proof connection. For each 3RB22/23/24 overload relay, you need a 3RB29 current measuring module and a connecting cable. In addition, you can use function expansion modules to optimize the auxiliary contacts for the functionality required. Simple, efficient, always up-to-date - the SIRIUS modular system.
