The invention refers to an electronic device that consists of two cards, one for the control and general processing, and the other for supplying power and acquiring data, these being communicated therebetween by the asynchronous serial format USART. A module that uses a wireless protocol is connected to a computer, this latter element acting as a master, the module being communicated in a wireless manner by radiofrequency with each one of the devices (control card), figure 4. Each system to be controlled and supervised is connected to the aforementioned device. A set of frequencies is intended to start the processes to be performed in each of the systems connected to the device. The master (PC) includes software tools for acquiring information from the system processes, sending control actions to the actuators and registering the variables of the required processes in each system. The digital outputs of the power card are electrically insulated by opto insulators that guarantee the sa fety of the control card and their components in case of faults. The use of the card keyboard and screen is useful for performing acquisition configurations such as the clock, the sample time and events timing.
