MS-VMA1630-1 Johnson Controls Controller

Overview

The Johnson Controls MS-VMA1630-1 is a programmable digital controller specifically designed for Variable Air Volume (VAV) applications within the Metasys Building Automation System. It features an integrated digital pressure sensor, a damper actuator, and a 32-bit microprocessor to provide precise control over airflow, temperature, and pressure. Its compact package size facilitates quick field installation and efficient use of space without compromising performance.

Features

• Standard BACnet protocol for interoperability with other building automation products.
• Standard hardware and software design to support uniform installation and commissioning workflows.
• Switchable communications between BACnet MS/TP and N2 protocols.
• Auto-tuned control loops that reduce commissioning time and mechanical wear.
• Universal inputs and configurable outputs providing extensive application flexibility.
• Support for wireless field bus interfaces and Bluetooth wireless commissioning.

Specifications

• Supply Voltage: 24 VAC nominal, 50/60 Hz.
• Power Consumption: 10 VA typical, 14 VA maximum.
• Points Profile: 3 Universal Inputs, 3 Binary Outputs, and 2 Configurable Outputs.
• Air Pressure Sensor Range: -1.5 to 1.5 inches W.C.
