Emerson Affinity VFD Drives

The Emerson / Control Techniques Affinity drive is specifically designed with building automation in mind for variable speed control of HVAC systems.

The Affinity drive can be used as a standalone motor controller or integrated into a building automation system using analog and digital I/O or serial communications. The base drive incorporates a RS-485 serial communications port that is selectable between BACnet, Metasys N2 or Modbus RTU. LonWorks, Ethernet, Profibus and Devicenet connectivity is achieved with the addition of plug-in Solutions Modules.
