Considered solid state because they don’t have any moving parts, these timer relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, preventing damage to your components from voltage spikes, amplifying the relay's signal, and reducing signal interference. They have multiple timing functions, so you don’t need to swap out your relay if you want to change their function.

Reduce voltage fluctuations and stress on shafts and bearings when starting up three-phase motors. These timer relays start with motor contacts in a star configuration, then switch to a delta configuration after a set delay.
