High‑capacity, open application control for complex air‑side, water‑side, and plant systems
The i‑Vu® UC Open XP (OPN‑UCXP) delivers powerful, flexible control for advanced HVAC and building applications, combining expanded I/O capacity, open BACnet communication, and seamless integration with the Carrier i‑Vu® Building Automation System.
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 controller provides 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. The UC Open XP also provides support for 24 additional I/O points through the use of the UC Open XP IO Expander. When combined, these controllers can support up to 48 total I/O points for even greater flexibility.
