Flexible I/O expansion for high‑capacity UC Open XP control applications
The i‑Vu® UC Open XP IO (OPN‑UCXPIO) expands the input and output capacity of the UC Open XP controller, enabling scalable control of complex air‑side, water‑side, and plant systems while maintaining seamless integration with the Carrier i‑Vu® Building Automation System.
Adds additional I/O point capacity to the OPN-UCXP controller. 16 inputs/8 outputs. Universal programmable controller provides auxiliary building control to interface with air handlers, chiller plants, hot water systems, lighting, and other HVAC equipment.
The UC Open XP IO expander adds additional I/O point capacity to the UC Open XP Controller. These controllers provide auxiliary building control to interface with air handlers, chiller plants, hot water systems, lighting, and other HVAC equipment. The UC Open XP’s factory engineered control programs provide simple building integration for commercial applications with 24 I/O point capability. When the UC Open XP IO expander is added to the UC Open XP controller, up to 24 additional I/O points are available. Together, these controllers support up to 48 total I/O points for even greater flexibility.

It expands the number of available input and output points for a UC Open XP controller, supporting more complex control applications.
No. It is designed to operate as a remote I/O expansion module connected to a UC Open XP controller.
The module supports binary inputs with pulse counting and universal analog inputs for temperature, contact, and voltage sensing.
Yes. Its remote mounting capability and simple Xnet connection make it well suited for retrofit and system expansion projects.
