REMOTE LOAD CONTROL DEVICE Russian patent published in 2024 - IPC G01R31/50 H02J13/00 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electronic engineering and can be used in automated process control systems (APCS). Remote load control device consists of a controller, first, second and third control relays, first, second and third current sensors, first, second and third current-limiting resistors. Remote control device has the following capabilities: in the “Load control” mode, it connects or disconnects the load from the power supply in response to commands from external devices; in “Control” mode automatically tests connecting lines for breakage and short circuit; controls its own performance; informs external devices on occurrence of such emergency situations as break or short circuit of load, break or short circuit of connecting lines, as well as on own failure.

EFFECT: providing continuous monitoring of both its own operability and integrity of connecting lines connecting the remote control device to the power source and the load.
