3RH2422-1BB40
The Siemens SIRIUS 3RH2422-1BB40 is an S00 latching contact relay with 2 normally open and 2 normally closed contacts, a DC 24V coil, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.
Product Positioning
The 3RH2422-1BB40 belongs to the SIRIUS 3RH24 series of 4-pole latched contact relays with a DC 24V coil. It can be used with a 24V DC power supply and PLC control system. After the contact is activated, it is maintained by mechanical latching. It is suitable for control and interlocking applications that require the state to be retained after a power outage.
Core Product Advantages and Features
Mechanical bolt retention
After the coil is activated, the contact state is maintained by a mechanical latch. When the control power is interrupted, the contact will not automatically reset, thus preserving the control state.
2NO+2NC contacts
It provides 2 normally open and 2 normally closed contacts, which can switch between normally open and normally closed signals simultaneously to meet interlocking and status feedback requirements.
DC24V coil
DC 24V coil, compatible with 24V DC power supply and PLC control system.
S00 size DIN rail mounting
S00 size, can be directly snapped onto 35mm DIN rail, screw terminal wiring is secure and easy to maintain inside the panel.
