Auxiliary switch, electron. delayed, OFF-delay with auxiliary voltage
Solid-state time-delayed auxiliary switch OFF delay With control signal Relay 1 NC + 1 NO 24...240 V AC/DC Time range 0.05...100 s Can be snapped on at the front For 3RT2 S00-S3 contactors and 3RH2 S00 contactor relays Screw terminal Varistor for attenuation of the contactor coils integrated Solid-state time-delay auxiliary switch SIRIUS 3RA28 for the delayed switching of downstream circuits for mounting on 3RT2 contactors and 3RH2 contactor relays.The electronically delayed auxiliary switches offer a high level of setting accuracy by means of switchable time ranges and have an integrated electrical interlock and a factory-fitted varistor (protective circuit). The simple plug-in facility requires no tools and permits the implementation of controller-independent time functions without any additional wiring. This enables you to avoid wiring errors and to reduce testing costs. The front mounting on the devices saves you space on the DIN rail. Thanks to international approvals (e.g. IEC, CCC, UL/CSA), the devices can be used worldwide.The solid-state time-delay auxiliary switches are available for 3RT2 contactors and 3RH2 contactor relays 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.For the electronically delayed auxiliary switch, wiring kits and a sealable cover are available.SIRIUS relays - one range for every application.
