Why Choose the Finder RB.22.9.125.9021?
The Finder RB.22.9.125.9021 is a compact bistable plug-in relay designed for energy-efficient switching in control and automation systems. With a contact rating up to 8 A and a 110/125 V AC/DC control input, this relay maintains its switching state without continuous coil power, making it ideal for applications where power consumption, heat dissipation, and state retention are critical.
Supplied as a plug-in relay, it is intended for use with compatible relay sockets, enabling fast replacement and simplified maintenance in control panels and automation cabinets.

Frequently Asked Questions
What does bistable mean on this relay?
A bistable relay latches in its last switching position and does not require continuous coil power to maintain that state, reducing energy consumption.
What voltage is required to operate the relay?
This model operates on a 110/125 V AC/DC control signal, providing flexibility across AC and DC control systems.
What loads can the contacts switch?
The contacts are rated up to 8 A. Always size the relay appropriately for the load type and apply suitable suppression for inductive loads.
How is this relay installed?
It is a plug-in relay designed to be used with a compatible Finder socket, allowing fast installation and easy replacement.
Why choose a bistable relay instead of a standard relay?
Bistable relays are ideal when you need to maintain a switching state during power loss or minimise coil power consumption and heat generation.
