The AMC turned out to be a transition product between the Multifunction Controller and the Process Manager.  Among the different generations of controller used on Honeywell's Data Hiway, the AMC would be easily be voted most-reliable.

We have an ample stock of Advanced Multifunction Controllers and replacement parts available.  If you need a complete controller, send us your I/O configuration, and specify whether or not you require redundancy (controller and/or I/O).
