A Safety Isolated Relay is a type of relay used to isolate control circuits from power circuits. It is designed with an electrically isolated mechanism that ensures that control and power circuits do not interfere with each other, even if one of the circuits experiences a fault. The device typically works by opening or closing contacts based on an input signal while maintaining electrical isolation between the high-voltage power circuit and low-voltage control circuit. This function is critical in preventing short circuits, electrical interference, and other hazards that could damage sensitive components or pose risks to operators.
