After receiving control commands from DCS main controller, the internal drive circuit excites the coil of corresponding relay. The mechanical contact acts to realize connection or disconnection of external passive circuits. The arc suppression circuit eliminates electric arc generated during contact switching. The status feedback circuit transmits relay action state back to main controller to complete closed-loop control.
