Siemens 6FX1120-2CA00 Safety Relay Module is a 24 VDC coil safety relay from Siemens’ 6FX family, designed to provide fail‑safe switching for safety circuits in automation environments. This compact module serves as a dedicated safety interface used to implement protective functions—such as interlocks and safety‑related signaling—within a broader control system and is typically paired with Siemens safety controllers and other 6FX/6ES safety devices to form a compliant safety chain.
