Information About AS-UNT-111-1
The AS-UNT-111-1 digital controller is part of the Johnson Controls Metasys family, offering advanced control functions for a wide range of HVAC applications. Engineered to manage both binary and analog signals, the unit supports 6 binary outputs for switching operations and 2 analog outputs for modulating control signals such as valve or damper positions.
Equipped with N2 bus isolation, the controller ensures reliable network communication and immunity from electrical interference—critical for maintaining system stability in building automation environments. Its TRIAC output operation is fully selectable, allowing high-side or low-side switching depending on load requirements.
The AS-UNT-111-1 operates on 24 VAC and supports a broad ambient temperature range (32°F to 140°F), making it adaptable to typical mechanical room conditions. Quick-connect spade lug terminals simplify wiring and installation.
Internally, the controller contains robust memory for program and data handling, including 8K EEPROM, 64K ROM, and 32K RAM. It supports both Zone Bus and N2 communication architectures and is UL-listed and CSA-certified for compliance in building automation applications.
Key Features:
- Unitary controller for packaged HVAC systems
- 6 analog inputs and 4 binary inputs
- 6 binary outputs and 2 analog outputs
- Selectable TRIAC high-side or low-side operation
- N2 isolated communication for enhanced reliability
- Quick-connect spade lug terminals
- 24 VAC operation
- EEPROM, ROM, and RAM memory onboard
- UL-listed and CSA-certified
- Wide operating temperature range
A versatile and robust unitary controller designed for Johnson Controls Metasys building automation systems, offering multi-input and multi-output HVAC control with N2 isolated communications and configurable TRIAC operation.
