AP-VMA1440-0

The Johnson Controls AP-VMA1440-0 VMA controller is a VMA or Variable Air Volume Modular Assembly controller. It is part of the VMA1430 line of controllers in the VMA 1400 series. The AP-VMA1440-0 controller is designed to provide efficient air volume control in various HVAC applications in a Johnson Controls Metasys Zoning system package. This VMA controller operates on a supply voltage range of 20-30 VAC at 50 or 60 Hz, and it consumes up to 10 VA of power. Additionally, it supports an optional 24 VAC fuse current rating of 2.0 amperes. For ease of installation and communication, the AP-VMA1440-0 controller is equipped with 6.3 mm (1/4 in.) spade lugs for terminations and communication screw terminals. It supports the N2 Bus and Zone Bus serial interface options. The N2 controller addressing for the AP-VMA1440-0 controller can be conveniently set using a DIP switch with address options ranging from 1 to 253. Addresses 254 and 255 are reserved for specific purposes. Mounting the AP-VMA1440-0 controller is straightforward. It comes with a single screw to secure it to the VAV box. The actuator torque rating is a minimum of 4 N⋅m (35 lb⋅in), ensuring effective operation. The AP-VMA1440-0 is built to withstand various ambient operating conditions. It supports an operating temperature range of 0 to 50°C (32 to 122°F) and an operating relative humidity range of 10 to 90% (non-condensing). It also supports a storage temperature range of -40 to 70°C (-40 to 158°F) and a storage relative humidity of 10 to 90% (non-condensing). The AP-VMA1440-0 controller is compact and space-efficient with dimensions of 153 x 102 x 102 mm (6 x 4 x 4 in.). The controller’s shipping weight is 1.3 kg (2.8 lbs).
