Siemens - 3RA2811-1CW10 ELECTRONIC TIMING RELAY ON DELAY WITH SEMICONDUCTOR OUTPUT 24-240 V AC/DC TIME RANGE 0.05...100 S CAN BE SNAPPED ON AT THE FRONT FOR CONTACTORS 3RT2 S00/S0 AND AUXILIARY CONTACTOR 3RH2 S00 SCREW TERMINAL VARISTOR FOR ATTENUATION OF THE CONTACTOR C

electronic timing relay, ON-delay, with semiconductor output, time range 0.05-100 s, 24-240 V AC/DC, 50/60 Hz, varistor for attenuation of the contactor coils integrated, screw terminal, can be snapped on at the front on contactors 3RT2.1 / 3RT2.2 and auxiliary contactors 3RH2 function module SIRIUS 3RA28 for direct-on-line starting for mounting on 3RT2 contactors and 3RH2 contactor relays for switching operations involving time delays in control, starting, protection and regulation circuits, e.g. for cascaded motor startup or fan running-on control.The simple plug-in facility requires no tools and permits the implementation of controller-independent time functions without any additional wiring. In this way, you avoid wiring errors and reduce testing costs. The front mounting on the devices saves you space on the DIN rail. No additional protective circuit is necessary. Thanks to international approvals (e.g. IEC, CCC, UL/CSA), the devices can be used worldwide.The function modules are available for 3RT2 contactors and 3RH2 auxiliary switches in sizes S00 to S3. They can be supplied with a flexible wide voltage range of 24-240 V AC/DC, selectable outputs 1 NO + 1 NC or 1 C and with screw or spring-loaded terminals.Wiring kits and a sealable cover are available for the function modules.SIRIUS relays - one range for every application.
