The DMC-1700 Series of ISA bus motion controllers received their first major upgrade and are now available with up to 80 I/O channels and firmware that doubles the number of multitasking threads. Dubbed the DMC-1718, -1728, -1738, and -1748, they provide an additional 64 digital I/O over their predecessors. The buffered I/O is accessible via two 50-pin ribbon cables that plug directly into OPTO 22 PO Series, Greyhill 70, or Greyhill HL Series expansion racks. In addition, engineers added new firmware that doubles the multitasking threads from four to eight while adding tangent and arc tangent functions, IF/ELSE constructs, and speed control around corners. Each card controls any combination of from one to eight axes using step motors, servo motors, and hydraulics. Galil Motion Control, Product Code 4209.
