Product Description P/N: MS-VMA1620-0
Description
The Johnson Controls MS-VMA1620-0 is an integrated Variable Air Volume (VAV) controller and actuator designed to regulate airflow and temperature in commercial HVAC systems. Operating from a 24 VAC Class 2 power supply, the MS-VMA1620-0 combines programmable control logic, an integrated actuator, and BACnet MS/TP communication to simplify VAV box control. Although discontinued by the manufacturer and replaced by the MS-VMA1630-1, it remains a dependable replacement for maintaining existing Metasys building automation installations.

Information About MS-VMA1620-0
The MS-VMA1620-0 is a member of the Johnson Controls VMA16 Series within the Metasys building automation platform, developed as an integrated VAV controller and actuator for pressure-independent air terminal units. It combines a programmable controller, actuator, and airflow sensing capabilities into a compact assembly that reduces installation time and wiring requirements. The controller communicates over BACnet MS/TP using the FC Bus and SA Bus, allowing seamless integration with Metasys supervisory controllers and network sensors. Its integrated actuator provides 35 inch-pounds of torque with a 60-second stroke time, making it suitable for commercial office buildings, healthcare facilities, educational campuses, and other HVAC applications.
Key Features:
- Integrated VAV Controller and Actuator: Combines programmable control and damper actuation in a single assembly.
- BACnet MS/TP Communication: Supports integration with Johnson Controls Metasys building automation systems.
- 24 VAC Class 2 Power: Operates from a standard HVAC control power source.
- Manual Override Function: Allows manual damper positioning during commissioning and maintenance.
- High Torque Actuator: Produces 35 inch-pounds of torque with a 60-second stroke time.
- Flexible Input and Output Configuration: Provides one universal input, three binary outputs, and two configurable outputs.
- Power-Limited Terminals: Uses Class 2 power-limited wiring for safe field installation.
- Replacement Model Available: Superseded by the Johnson Controls MS-VMA1630-1 for newer installations.
The MS-VMA1620-0 delivers the reliability and precision required for variable air volume control and commercial HVAC automation systems.
