Limit Interface Board for the HoPEC System Controller

The Limit Interface Board is one of our newest upgrades to the HoPEC System, meticulously designed to simplify and enhance the control of your elevator or dumbwaiter project. This board offers a seamless user experience, versatile compatibility with a comprehensive range of limit sensors.


Key Features:

  • Effortless Limit Switch Connection: The Limit Interface Board features clearly labeled screw terminals, making it exceptionally easy to connect elevator limit switches for Top, Middle, Bottom and backup limit positions. The hassle of individual wiring is a thing of the past.

  • Daisy Chain Connectivity: The true innovation lies in our daisy chain connectivity solution. This board allows you to link multiple Limit Interface Boards together using standard network cables, eliminating the need for intricate limit switch wiring.

  • Connection Capacity: One board can handle all 5 possible limit locations or you can use the daisy chain feature to reduce the amount of wiring required to hook the limit switches to the system. For example, you can connect the top floor and the top backup limit switch on one board and then daisy chain a second board that will connect the bottom floor and the bottom limit switch. If your switches are close in proximity, use one board for all of them.

  • Universal Limit Switch Compatibility: This board is designed to work seamlessly with a wide range of elevator control limit switches. Whether your project requires standard mechanical switches or hall effect sensors, it offers the flexibility to match your specific needs.

  • Compact Design: The Limit Interface Board is ingeniously compact, designed to fit perfectly into a standard 2-gang electrical box. This space-efficient design ensures a tidy and organized control system installation.



  • Simplified Installation: The standout feature of this board is its daisy chain connectivity. By using standard network cables, you eliminate the need for intricate, time-consuming wiring. This results in a cleaner and more organized control system with fewer possible points of failure due to wiring problems.

  • Versatile Compatibility: Whether you choose mechanical limit switches or hall effect sensors, this board accommodates your specific needs, making it suitable for a wide range of elevator and dumbwaiter projects.

  • Future-Ready and Backward-Compatible: The Button Interface Board is designed for the upcoming HoPEC version 8.0 system, offering advanced capabilities. However, it's equally capable of functioning seamlessly on the current HoPEC 7.x system. This ensures that you can enjoy its benefits regardless of your system version.


The Limit Interface Board takes the complexity out of elevator control limit switch wiring, offering a smarter, more efficient solution.
