A safety relay is an essential component in industrial automation systems designed to ensure the safety of machinery and personnel. It monitors safety devices, such as emergency stop buttons and safety light curtains, to detect any faults or unsafe conditions. If a problem is identified, the safety relay quickly interrupts the power supply to the machinery, preventing accidents. These relays are built to meet strict safety standards, often categorized under Functional Safety guidelines. They provide a reliable way to manage safety functions, ensuring that equipment operates within safe parameters. By using a safety relay, companies can enhance workplace safety and comply with regulatory requirements.
