General Purpose Controller
Universal programmable controller provides auxiliary building control to interface with lighting, fans, pumps, and other HVAC equipment. 6 inputs/5 outputs.
The UC Open controller provides auxiliary building control to interface with lighting, fans, pumps, and other HVAC equipment. The UC Open’s factory-engineered control programs provide simple building integration for commercial applications with 11 I/O point capability.
| 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 (9600 bps, 19.2 kbps, 38.4 kbps, and 76.8 kbps) 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 | 6 inputs: Configurable for thermistor or dry contact. Inputs 1 and 2 are also configurable for 0-5 VDC sensors. AIs have 12 bit A/D resolution. |
| Outputs | 5 binary outputs: Relay contacts rated at 1 A max @ 24 VAC/VDC, configured normally open. |
| 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 indicators for communications, run status, error, and power. |
| Controller Addressing | Rotary DIP switches set BACnet MS/TP MAC address of controller. |
