METHOD OF CONTROL OF GROUP OF ELECTROMAGNETIC MECHANISMS, MAINLY SHUTDOWN VALVES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC H01F7/18 

FIELD: electricity.

SUBSTANCE: device for control of the group of electromagnetic mechanisms contains a microcontroller with I/O port to receive control information and to transmit information of solenoid valves state, input device to receive input signals and output device to form control signals, control panel, I/O port for software input. The control device contains two controlled keys per each valve, their inputs are connected with outputs of the input device of the microcontroller, voltage source, signal generator of voltage presence for electromagnetic mechanisms switching on. Voltage source output is connected with inputs of the first controlled keys, and their outputs are connected with the electromagnetic mechanisms of valves opening. Input of the signal generator of switching on voltage presence is connected with output of the voltage source. The device has signal generators of the valve state sensors and emergency signal generators of monitoring channels. Inputs of the second controlled keys are connected with output of the voltage source, and their outputs are connected with the electromagnetic mechanisms of valves closing.

EFFECT: higher reliability.
