Standard System 4® Controller
When originally released our standard System 4® Door Controller had greater functionality and unprecedented efficiency than controllers before it. Rytec’s next-generation System 4 Door Controller took performance to a whole new level. It was faster, smarter, smaller and easier to install than other high-speed door controllers. Its intelligent processor and variable frequency drive generates an energy-efficient speed curve for smooth motion, soft starting and soft stopping.
As we transition to the new System 4+, the standard System 4 still provides great functionality and is controlling thousands of doors out in the field today – but if additional connectivity is desired do not hesitate to contact your Rytec representative to see if upgrading is right for you.
