Siemens 3RH2131-1XF40-0LA2

Auxiliary relay for rail 3S +1Ö DC 72-125V, 0.7...1.25 US, with integrated varistor, size S00, screw terminal 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 for railway applications. The SIRIUS 3RH2 auxiliary relays feature standardized terminal designations and a reliable, time-saving connection technology. Output multiplication 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 worldwide use due to relevant approvals (e.g., IEC and UL/CSA). This variant is characterized by an extended operating and temperature range for harsher environmental conditions. They are available in AC or DC actuation and come with screw or spring clamp technology. The basic version of the auxiliary relays is 4-pole and can be expanded to up to 8 poles with snap-on auxiliary contacts. 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.
