Project:      Conversion of Cutler-Hammer PLC to Allen-Bradley for Gasket Press 

Client:      Valley Products Company - Decatur, AL


Project description:

An existing, automatic gasket pressing machine which utilized a 5-year-old Cutler-Hammer D500 PLC was retrofitted with an Allen-Bradley SLC-500 series PLC. The new system consisted of an A-B SLC-5/03 CPU, various input/output modules and two quadrature encoder cards. It was necessary to remove the existing C-H PLC from the control panel. The new A-B PLC was installed in the panel and the existing wire was used. The existing C-H D500 ladder logic program was converted to A-B SLC-500 format. The system was then debugged and proven to operate as before the retrofit.
