Overview
The Square D 8005 Model 50 is a modular programmable logic controller from the SY/MAX Class 8005 series. This processor is part of the SY/MAX Class 8005 Series A-2 (revision 1.05) Model 50 Programmable Controller family. The processor unit comprises a processor, built-in power supply, and a base for attaching two I/O modules. The SY/MAX line of PLCs continues to be supported by Schneider Electric, though production has been discontinued and this unit is now available as a used/surplus component.
