In industrial environments, safety is paramount to protect both workers and machinery from potential hazards. One of the key components in achieving safety is the safety relay, specifically the SO 12100 Safety Relay, which plays a critical role in ensuring that machines and systems remain safe during operation. This article will explore what the SO 12100 Safety Relay is, how it works, its importance in industrial automation, and its compliance with safety standards.

What is the SO 12100 Safety Relay? The SO 12100 Safety Relay is a specialized device designed to monitor and control safety systems in industrial machinery. It acts as an intermediary between safety devices (such as emergency stop buttons, safety doors, light curtains, and more) and the machine’s control circuit. When any safety device is activated, the safety relay ensures that the machine’s power supply is immediately cut off or the necessary safety protocols are followed. The SO 12100 Safety Relay is commonly used in safety circuits where the goal is to minimize the risk of injury or damage. It is designed to meet rigorous standards for safety and reliability, ensuring that safety measures function correctly even under fault conditions.
