Product Description
. . . . . MS-VMA1628-x 32-bit, Integrated VAV Controller and DPT, 3 UI, 3 BO, and 2 CO; 24 VAC; FC Bus, and SA Bus (No Actuator) - The VMA1615/1626/1628/1630 programmable digital controllers are designed for Variable Air Volume (VAV) applications that communicate through the BACnet® MS/TP or N2 protocol. These Variable Air Volume Modular Assembly (VMA) controllers feature combinations of an integral digital pressure sensor (DPT), a damper actuator, and a 32-bit microprocessor. The VMA1626 has an actuator but does not contain a DPT. The VMA1628 model has a DPT but does not contain an actuator. The controllers' small package size facilitates quick field installation and efficient use of space without compromising high-tech control performance. These VMA controllers connect easily to the wired and wireless network sensors for zone and discharge air temperature sensing.. Johnson Controls. Johnson Controls. MS-VMA1628-1.
