Description
The AC Controller provides automatic operation (a closed-loop system) for the MagnaValve®. The
feedback from the controller allows the MagnaValve to regulate steel shot in shot peening and blast
cleaning applications where accurate and repeatable ow rates are desired. The controller may operate
as a stand-alone control or work with a customer’s programmable controller via standard analog 0-10 Vdc
interface. Alarm contacts will notify of a high or low motor current outside of an adjustable bandwidth.
A clear and comprehensive installation manual simplies installation for the AC Controller and the
product is supported by the Electronics Inc. application engineering sta.
