Product Description
Finder RB.22.9.250.0000 Bistable Relay
Bistable Relay - 2C0 8A - Input 250 V DC
Finder RB.22.9.250.0000 Bistable Relay
Finder RB.22.9.250.0000 Bistable Relay - 2CO 8A (220-250V DC)
The Finder RB.22.9.250.0000 is a high-performance bistable (latching) relay engineered for heavy-duty industrial automation and high-voltage DC control environments. Featuring a 2CO (Changeover) contact configuration with an 8A rating, this model is specifically optimized for operations within the 220V to 250V DC range. Unlike standard monostable relays, the bistable mechanism utilizes a mechanical latching design that retains its contact position even after the electrical control pulse is removed. This functionality ensures maximum energy efficiency by eliminating continuous coil power and provides a reliable mechanical "memory" of the last state, making it an essential component for power distribution, safety-critical circuits, and high-efficiency industrial designs.
Technical Excellence
- Bistable Latching: Maintains contact state indefinitely after an impulse, ensuring zero power draw in a static state
- 2CO Contact Configuration: Features 2 independent Changeover contacts for versatile circuit control
- High-Voltage DC Input: Specifically engineered for industrial systems operating between 220V and 250V DC
- 8A Rated Capacity: Robust switching power suitable for various industrial and auxiliary loads
- Impulse Driven: Requires only a brief electrical pulse to switch states, significantly reducing thermal load
- Industrial Grade Build: Designed for high-frequency operation and long mechanical service life
Operational Advantages
- Energy Efficiency: Zero energy consumption in the maintained position prevents coil overheating
- State Persistence: Reliable mechanical memory ensures contacts stay in the last position during power loss
- AgNi Contact Material: High-quality silver-nickel alloy provides superior conductivity and durability
- Vibration Resistant: Robust latching mechanism prevents unintended state changes due to mechanical vibrations
- Compact Footprint: Provides significant switching capacity in a standardized industrial housing
- Global Standards: Manufactured by Finder to meet rigorous international CE and EAC quality certifications
