Product description
KDG1140 explosion-proof and intrinsically safe power-off feeder for coal mines (hereinafter referred to as the "power-off feeder") is a mining control product, mainly used to detect the current-carrying condition of underground electrical equipment and receive substation's power-off commands to perform power-off control. The power-off feeder supports digital communication and is compatible with level power-off.
Features
◎Normally open and closed contact output;
◎Both normally open contacts and normally closed contacts can output the corresponding control state according to the input signal and keep it;
◎The output of the power-off feeder can meet the needs of AC or DC control;
◎Monitoring and display of the controlled equipment's feeding status and signal output;
◎Power supply indication, output status indication, and RS485 status indication.
