The 8 Output Module PTC is a fuse card with eight PTC fuses. The card is equipped with a total alarm and memory function, and is used to protect against damage caused by overcurrent or short circuit.
*Positive Temperature Coefficient
PTC stands for “Positive Temperature Coefficient,” and it is a type of thermal fuse. The fuse is used to protect electrical circuits. The fuse works by changing its resistance properties when it gets too hot due to high current. When the current becomes too high, the temperature in the fuse increases, which makes it less conductive and restricts the flow of current. When the temperature in the fuse drops, the fuse returns to its normal state and allows the current to pass through as usual.
