Contactor relay for railway, 2 NO + 1 NC, 24 V DC, 0.7 ... 1.25* US, with integrated suppressor diode, Size S00, ring cable lug connection suitable for PLC outputs Auxiliary contactor SIRIUS 3RH2 for switching the control signals in the control circuit.The SIRIUS 3RH2 contactor relays have standard-compliant terminal designations and a reliable and time-saving connection technology. Thanks to the multiplication of outputs, simultaneous switching of several auxiliary circuits is possible. All contacts are available with positively driven operation for safety applications as well as SUVA versions. The contactor relays are climate-resistant, have a high contact reliability and are suitable for use worldwide thanks to the corresponding approvals (e.g. IEC and UL/CSA).They are available with AC or DC operation and with screw or spring-loaded terminals. The basic version of the contactor relays is a 4-pole design which can be extended up to 8 poles by means of snap-on auxiliary switches
