MS-VMA1630-0 Johnson Controls Controller

Overview

The Johnson Controls MS-VMA1630-0 is a 32-bit integrated Variable Air Volume (VAV) controller, actuator, and digital pressure sensor (DPT) designed for VAV applications. Operating within the Metasys system, it optimizes airflow in multi-zone HVAC systems and supports seamless integration via switchable BACnet MS/TP or N2 communication protocols. Its compact package size facilitates quick field installation and efficient use of space.

Features

• Dual Protocol Support: Switchable between BACnet MS/TP and N2 protocols for enhanced interoperability.
• Advanced Adaptive Control: Employs patented P-Adaptive and Pattern Recognition Adaptive Control (PRAC) technologies for continuous loop tuning.
• All-in-One Design: Integrates a 32-bit microprocessor, digital pressure sensor, and damper actuator into a single unit.
• Wireless Capability: Supports ZFR Wireless FC or SA Bus interfaces for flexible, wire-free deployment.
• Easy Commissioning: Features automatic BACnet discovery and Bluetooth wireless commissioning options.

Specifications

• Microprocessor: 32-bit Renesas microcontroller.
• Memory: 1 MB Flash Memory and 512 KB RAM.
• Inputs and Outputs: 3 Universal Inputs (UI), 3 Binary Outputs (BO), and 2 Configurable Outputs (CO).
• Supply Voltage: 24 VAC nominal (20 VAC minimum to 30 VAC maximum) at 50/60 Hz.
• Power Consumption: 10 VA typical, 14 VA maximum (excluding peripheral loads).
• Operating Temperature: 0°C to 50°C (32°F to 122°F).

Applications

• Designed primarily for pressure-independent Variable Air Volume (VAV) cooling and reheat box control in commercial HVAC installations.
• Ideal for building automation systems requiring integration into a Metasys BAS network.
• Suitable for use in environmental air spaces (plenums) and qualified for smoke control applications under Metasys Release 8.1.
