Description
The Johnson Controls MS-VMA1930-0 is an integrated VAV controller designed for Variable Air Volume applications on BACnet/IP building automation networks. It combines a differential pressure sensor, damper actuator, and 32-bit microprocessor in a compact assembly that supports efficient installation while providing control, monitoring, and communication.
It includes two Ethernet ports for BACnet/IP communications, a 6-pin sensor port for TE-7xx Series non-communicating sensors, and onboard memory with 16 MB serial flash and 8 MB SDRAM. An integral real-time clock supports schedules, calendars, and trends, allowing continued operation as a standalone controller when disconnected from the network.
Frequently Asked Questions
What sensors does the MS-VMA1930-0 support?
It includes a 6-pin port for TE-7xx Series non-communicating sensors and an SA Bus for wired and wireless network sensors covering zone and discharge air temperature.
Can the MS-VMA1930-0 operate without a network connection?
Yes. An integral real-time clock lets it run schedules, calendars, and trends as a stand-alone controller when offline from the Metasys system.
Which supervisory devices is the MS-VMA1930-0 compatible with?
It communicates over BACnet/IP with NAE55, NAE85, and ODS supervisory devices, and is BTL listed as a BACnet Advanced Application Controller.
