Electronic time relay with off-delay with control signal and semiconductor output AC/DC 24-90 V Time range 0.05...100 s Can be snapped on the front for 3RT2, S2, S3 contactors and 3RH2 contactor relays S00 Spring-loaded connection SIRIUS 3RA28 function module for direct start for attachment to 3RT2 contactors and 3RH2 contactor relays for time-delayed switching operations in control, starting, protection and regulating circuits, e.g. cascaded motor start-up or fan run-on control. The simple and tool-free attachment enables the implementation of control-independent time functions without additional wiring. This avoids wiring errors and reduces testing costs. By attaching the devices to the front, you save space on the DIN rail. Additional protective circuitry is not required. The devices can be used worldwide thanks to international approvals (e.g. IEC, CCC, UL/CSA).The function modules are available for 3RT2 contactors and 3RH2 auxiliary switches in sizes S00 to S3. Available with a flexible wide voltage range AC/DC 24-240 V, selectable outputs 1 NO + 1 NC or 1 W and with screw or spring-loaded connection technology.Wiring kits and a sealable cover are available for the function modules.SIRIUS relays - a program for all situations.
