The safety module is composed of several relays and circuits. The safety function unit with redundant circuit is constructed by the contact force oriented relay and logic circuit. The purpose of this design is to complement each other's abnormal defects, thus to achieve a correct and low maloperation relay complete function, making less error, creating more safety.
