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.
General Purpose Controller
Universal programmable controller provides auxiliary building control to interface with air handlers, chiller plants, hot water systems, lighting, and other HVAC equipment.
| BACNet Support | Advanced application controller (B-AAC), as defined in BACNet 135-2001 Annex L |
| Communication Ports |
BACNet Port: EIA-485 port for BACnet MS/TP communications (baud rate is DIP switch selectable) Local Access port: For system start-up and troubleshooting (115.2 kbps) Rnet port: For connecting Carrier communicating room sensors and Carrier's touchscreen user interface |
| Inputs | 12 inputs: Configurable for 0-10V, RTD/Thermistor/Dry contact, or 0-20mA. Inputs 1 and 2 may be used for pulse counting. All analog inputs have 12 bit A/D resolution. |
| Outputs |
6 binary outputs: Configured as dry contact, normally open or normally closed. All binary outputs must be powered from a Class 2 power source. 6 analog outputs: 1 and 2 are configurable for 0-10V or 0-20mA; 3-6 are 0-10V only. Analog outputs have 8 bit D/A resolution. |
| Protection | Incoming power and network connections are protected by non-replaceable internal solidstate polyswitches that reset themselves when the condition that causes a fault returns to normal. The power, network, input, and output connections are also protected against voltage transient and surge events. |
| Real Time Clock | Battery-backed real time clock keeps track of time in event of power failure. |
| Battery | 10-year Lithium CR2032 battery provides a minimum of 10,000 hours of trend data & time retention during power outages. |
| Status Indicators | LED status of power, running, and errors. LED indicators for transmit/receive for BACnet port and for each of the 12 outputs. |
| Controller Addressing | Rotary DIP switches set BACnet MS/TP MAC address of controller. |
