ELECTROMECHANICAL BISTABLE RELAY

The bistable relays are mainly used for remote and automatic controls where there is often a need for contactors which have two stable contact positions, even in the dead state.

The application of alternate control pulses to the coils because the contacts to change from the one state to the other. If the supply is interrupted, the contacts remain in their previous position, even when the voltage is restored. The contacts are arranged symmetrically on both sides of relay coil and armature assembly in two stacks.

Electromechanical and solid state relays

For new applications where reliable operation is essential, in harsh environments, or in existing installations where an exact replacement is required

ABB electromechanical relays have protected the power system for more than 100 years, and with the proper inspection, maintenance, and testing techniques, these relays can guard the power system for many more years.

Solid state electronic components provide a similar function to electromechanical relays but do not have any moving components, increasing long-term reliability.
