MS-VMA16 Controllers

MS-VMA16 Controllers

Variable air volume modular assembly

VMAs are programmable digital controllers tailored for VAV applications that communicate via the BACnet Master-Slave/Token- Passing (MS/TP) protocol, which can be integrated to any supervisory controller capable of managing N2 Open networks and devices, such as the Network Communication Module (NCM) and Network Automation Engine (NAE).

Features

• 32-bit microprocessor ensures optimum performance and meets industry specifications.
• Universal inputs, configurable outputs and Point Expansion modules. Allow multiple signal options to provide input/output flexibility.
• Standard hardware and software platform.
• Auto Tuned Control Loops.
• A state-of-the-art digital non-flow pressure sensor to provide 14-bit resolution with bidirectional flow operation that supports automatic correction for polarity on high- and low-pressure DP tube connections; this pressure sensor eliminates high- and low-pressure connection mistakes.
• A fast response actuator that drives the damper from full open to full closed (90°) in 60 seconds to reduce commissioning time.
• Standard BACnet Protocol - BACnet Testing Laboratories™ (BTL) listing provides interoperability with other Building Automation System (BAS).
