In industrial automation, ensuring the safety of machinery and workers is of paramount importance. One key component that plays a critical role in this regard is the safety relay. Among the many types of safety relays available, the SO 12100 Safety Relay stands out due to its adherence to the internationally recognized standards for machine safety, particularly ISO 12100. This article delves into the essential aspects of the SO 12100 Safety Relay, highlighting its functions, applications, and how it enhances machine safety in industrial environments.

What is SO 12100 Safety Relay? The SO 12100 Safety Relay is a safety device designed to control the operation of machinery and equipment in a manner that ensures the safety of operators and other personnel. It operates as part of a larger safety system that includes emergency stop buttons, light curtains, and safety interlock switches. The safety relay’s main purpose is to monitor the machine’s operation, detect hazardous conditions, and trigger the appropriate safety mechanisms to prevent accidents. The SO 12100 relay is specifically designed in accordance with ISO 12100, an international standard that provides guidelines for risk assessment and risk reduction in machinery. The standard ensures that the relay can effectively meet performance levels required for safety-critical applications.
