Further details: Coupling auxiliary relay, 2 S + 2 Ö, DC 24 V, 0.7 ... 1.25* US, size S00, screw connection suitable for PLC outputs. Coupling auxiliary relay SIRIUS 3RH2 for switching control signals in the control circuit with direct connection capability to electronic controls. The SIRIUS 3RH2 coupling auxiliary relays have standardized connection designations and a reliable, time-saving connection technology. Output multiplication allows for the simultaneous switching of multiple auxiliary circuits. The contacts are available with forced guidance for safety applications as SUVA variants. The coupling auxiliary relays are climate-resistant, have high contact reliability, and are suitable for worldwide use due to corresponding approvals (e.g., IEC and UL/CSA). They are available in AC or DC operation and come with screw or spring-loaded technology. The extensive accessories of relays 3RT2 for sizes S00 to S3 can also be used for the coupling auxiliary relays 3RH2. The coupling auxiliary relays 3RH2 replace the proven series 3RH1. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
