Siemens Digital Industry Coupling Auxiliary Relay 3RH2122-2LB40: additional details
Coupling auxiliary relay for rail, 2 S + 2 Ö, DC 24 V, 0.7 ... 1.25* US, with integrated varistor, size S00, spring connection. The SIRIUS 3RH2 coupling auxiliary relay is designed for switching control signals in the control circuit with direct connection capability to electronic controls. The SIRIUS 3RH2 coupling auxiliary relays feature standardized connection designations and a reliable, time-saving connection technology. Through output multiplication, it is possible to switch multiple auxiliary circuits simultaneously. The contacts are available with forced guidance for safety applications, also as SUVA variants. The coupling auxiliary relays are climate-resistant, have high contact reliability, and are suitable for global use with appropriate approvals (e.g., IEC and UL/CSA). They are available for AC or DC actuation and come with screw or spring connection technology. The extensive accessories of the 3RT2 relays for sizes S00 to S3 can also be used for the 3RH2 coupling auxiliary relays. The 3RH2 coupling auxiliary relays replace the proven series 3RH1. Simple, efficient, always up to date - the SIRIUS system modular concept.
