Auxiliary relay for rail 2S + 2Ö, DC 24-34V, 0.7...1.25*US, with integrated varistor, size S00, spring-loaded connection suitable for PLC outputs. The SIRIUS 3RH2 auxiliary relay is designed for switching control signals in control circuits with significant fluctuations in control voltages under extreme conditions, such as in railway applications. The SIRIUS 3RH2 auxiliary relays have standardized connection designations and a reliable, time-saving connection technology. Output duplication allows for the simultaneous switching of multiple auxiliary circuits. All contacts are available with forced guidance for safety applications, including SUVA variants. The auxiliary relays are climate-resistant, have high contact reliability, and are suitable for global use with appropriate certifications (e.g., IEC and UL/CSA). This variant features an extended operating and temperature range for harsher environmental conditions. They are available with AC or DC operation and come with screw or spring-loaded technology. The basic version of the auxiliary relays is 4-pole and can be expanded to 8 poles with snap-on auxiliary switches. The extensive accessories of the 3RT2 relays for sizes S00 to S3 can also be used for the 3RH2 auxiliary relays. The 3RH2 auxiliary relays replace the proven 3RH1 series. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
