Electronic time relay, delayed on release, with control signal and semiconductor output. Time range 0.05-100 s, AC/DC 24-240 V, 50/60 Hz. Integrated varistor for suppressing relay coil transients. Screw connection, snap-on from the front for contactors 3RT201 / 3RT202 and auxiliary relays 3RH2. Function module SIRIUS 3RA28 for direct start, designed for mounting on contactors 3RT2 and auxiliary relays 3RH2 for time-delayed switching operations in control, starting, protection, and regulation circuits, e.g., cascading motor start or fan run-on control. The simple and tool-free snap-on design allows for the implementation of control-independent time functions without additional wiring. This helps avoid wiring errors and reduces testing costs. By mounting on the front of the devices, you save space on the DIN rail. An additional protective circuit is not required. The devices are globally applicable thanks to international approvals (e.g., IEC, CCC, UL/CSA). The function modules are available for contactors 3RT2 and auxiliary switches 3RH2 in sizes S00 to S3. Available with a flexible wide voltage range AC/DC 24-240 V, selectable outputs 1 S + 1 Ö or 1 W, and in screw or spring-loaded connection technology. Wiring kits and a sealable cover are available for the function modules. SIRIUS relays - a program for all cases.
