Information About MS-VMA1832-0
The MS-VMA1832-0 is a Johnson Controls VMA1832 programmable variable air volume controller developed for Metasys field-level building automation applications. Its compact 32-bit architecture integrates the controller electronics, a 4 newton-meter damper actuator, differential pressure sensing, universal inputs, binary outputs, and configurable outputs within one assembly. The controller can communicate through either BACnet MS/TP or N2 protocol and also provides a Sensor Actuator Bus connection for compatible network sensors and peripheral devices. Designed for 24-volt alternating-current operation, the MS-VMA1832-0 supports cooling with reheat and fan control and has been superseded by MS-VMA1832-1.
Key Features:
- Integrated Airflow Control: Combines programmable control, damper actuation, and differential pressure measurement for variable air volume terminal applications.
- 32-Bit Processing: Uses a 32-bit controller architecture for executing building automation control sequences and managing connected inputs and outputs.
- Integrated Damper Actuator: Provides a 4 newton-meter actuator for direct mounting and positioning of the variable air volume box damper shaft.
- Differential Pressure Sensor: Includes an integrated sensor with a measurement range from -1.5 to 1.5 inches of water column for airflow measurement.
- Flexible Input and Output Control: Provides three universal inputs, three binary outputs, and two configurable outputs for sensors, actuators, and controlled equipment.
- Dual Communication Capability: Supports selectable BACnet MS/TP or N2 communication over an RS-485 field bus.
- Sensor Actuator Bus Integration: Provides a dedicated bus for compatible Johnson Controls network sensors and other supported field devices.
- 24-Volt Operation: Operates from a nominal 24-volt alternating-current Class 2 power source at 50 or 60 hertz.
The MS-VMA1832-0 delivers the reliability and precision required for airflow measurement, damper positioning, zone temperature regulation, reheat control, and fan management in variable air volume systems.
