Programmable logic power source controller

The invention belongs to the technical field of power source control, and particularly relates to a programmable logic power source controller. The programmable logic power source controller comprises a power module, a CPLD and a peripheral circuit connected with the CPLD. The signal input end of the CPLD is respectively connected with a panel signal interface and an IO signal interface through a photocoupling unit. The output end of the CPLD is connected with a relay driving unit through a level switching unit. The power module provides corresponding direct-current working voltages for the CPLD, the panel signal interface, the IO signal interface, the photocoupling unit, the level converting unit and the relay driving unit. According to the programmable logic power source controller, the CPLD is adopted, a power system control mode can be changed according to actual needs, easy, rapid, reliable sequential logic control over the complex power system of a semiconductor packaging device is achieved, and reliabi
