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).
