Information About AS-UNT1126-0
The AS-UNT1126-0 is part of the Johnson Controls Facility Explorer and Metasys Unitary Controller family developed for distributed building automation systems. It combines analog and binary input/output capability with programmable control logic, allowing a single controller to manage complex HVAC sequences while communicating with supervisory controllers through the Metasys N2 bus. The controller supports numerous sensor types, configurable relay outputs, and analog control signals, making it suitable for controlling dampers, valves, fans, compressors, and other HVAC equipment. Its compact industrial design, wide operating temperature range, and flexible mounting options enable installation in commercial, institutional, and industrial control panels.
Key Features:
- Six universal analog inputs: Supports 1 kΩ RTD, 0–10 VDC, and 0–2 VDC input signals.
- Six binary inputs: Compatible with 24 VAC dry-contact field devices.
- Two analog outputs: Provides 0–10 VDC control signals for proportional actuators and valves.
- Six relay outputs: Class 2 relay outputs rated at 2 A for equipment control.
- Metasys N2 communication: Integrates directly with Johnson Controls building automation networks.
- Programmable HVAC controller: Supports custom application programming for various mechanical systems.
- Wide operating temperature: Reliable operation from -40°C to 60°C.
- Flexible installation: Supports DIN rail or surface mounting.
- Low power consumption: Requires only 7 VA excluding connected field devices.
- Multiple wiring options: Accepts spade lug or removable screw terminal connections.
- DIP switch addressing: Simple controller addressing for N2 network configuration.
- Industrial reliability: Designed for continuous operation in commercial HVAC environments.
The AS-UNT1126-0 delivers the reliability and precision required for HVAC automation, environmental control, and distributed building management systems.
