As industries worldwide embrace automation, the complexity of machines has increased. Consequently, there is a heightened responsibility to protect operators, maintenance personnel, and the surrounding environment from potential hazards. Safety relays play a pivotal role in this context by monitoring the status of safety devices such as emergency stop buttons, light curtains, and safety gates. Upon detecting a fault or unsafe condition, the relay can immediately deactivate the machine to prevent accidents, thereby safeguarding human life and minimizing equipment damage.
