The Classic PLC Infobase is an on-going project to amass and accumulate as much public data as is available on the legacy Programmable Logic Controllers and make the information available in an easy to search and use format.
Within the Infobase forums you will find an expansive and ever-growing listing of legacy PLC equipment and modules, which may include; descriptions, specifications, pinouts, hookups, images, and even repair tips.
