Abstract
The utility model provides a device control PCB board which comprises a PCB board body and a circuit attached to the PCB board. A component hole is arranged on the PCB board. The device control PCB board further comprises a first terminal, a second terminal and a control circuit. The control circuit comprises switch groups, current-limiting resistors, an interlock relay and LED indication lamps. A switch group comprises two switches. Each switch is connected in series with a current-limiting resistor and an LED indication lamp. Each switch group is connected with the interlock relay. One end of the control circuit is connected with an external power supply through the first terminal, and the other end is connected with an input end of an external PLC through the second terminal. When a user presses a button, the corresponding LED indication lamp emits light, the switches are switched on, and a given signal is input into a PLC input end. When the user releases the button, the switches are switched off. According to the device control PCB board provided by the utility model, the control circuit is integrated in the PCB board, thus the wiring is simple, and the manpower cost is effectively reduced.
