Product Positioning
The Siemens SIRIUS 3RH2122-1KB40 is an S00 frame coupled auxiliary contactor with a 24V DC coil and a built-in suppressed diode. It is suitable for driving PLC output circuits, adopts a screw terminal design, and provides 4 sets of contacts: 2NO and 2NC.
Core Product Advantages and Features
Built-in suppression diode
The coil has a built-in suppression diode to reduce the impact of voltage surges on the PLC output circuit during power outages.
Suitable for PLC output drivers
The voltage tolerance range is 0.7 to 1.25 times the rated value, and it is designed to be optimized for PLC output interface applications.
2NO+2NC quadrupole contacts
Two sets of normally open and two sets of normally closed contacts are provided in parallel, which facilitates the formation of signal interlocking and feedback circuits.
Screw terminal secure wiring
Traditional screw terminal design is suitable for automated control panels that require long-term stable operation.
