Since its inception in 1975 Autotech Controls division of AVG automation has been in the forefront of developing resolver based technology for the industry.  Through continuous innovation and by virtue of its vertical integration AVG Automation is able to bring to you the ruggedness and noise immunity of resolver based technology for the cost of optical encoders.  Over half a million AVG resolvers are in use all over the world to provide position/motion feedback to such controls as PLCs, CNCs, computer based controls and definite purpose OEM controls.

Back in 1985, AVG Automation revolutionized the encoder market by introducing the Digisolver; industry's first resolver based digital encoder that combined the ruggedness of a resolver with the reliability of solid-state circuitry.

In the late 80's, Autotech introduced the concept of resolver decoder module that plugs directly into the PLCs eliminating the need of stand alone decoder module.  In the world of proprietary PLCs and racks, these modules called BusModules provide the only "Universal" solution.  These modules are universal as the same module can be used in any of the supported PLC racks offering a common user interface (for a function) across different PLCs.
