The first Allen-Braley PLC was the 1750 PMC Programmable Matrix Controller, followed by the 1774-PLC, and then the 1772-PLC2. The I/O of the 1774 was the Bulletin 1778 Series, and the 1772 used the 1777 I/O initially, but that was replaced with the highly successful 1771 I/O system. The 1771 I/O system also introduced “Remote I/O.” That format was then used to develop the PLC-5, which fit into the 1771 I/O chassis.Allen-Bradley also introduced two small PLC’s in the 1980’s.
