What is Safety PLCs?

Safety PLCs (Programmable Logic Controllers) are specialized PLCs designed and certified for use in safety-critical applications. They incorporate redundant architectures, diagnostics, and rigorous self-testing capabilities to ensure reliable operation and prevent dangerous failures. They are commonly used in industrial automation to monitor safety sensors (e.g., light curtains, emergency stops) and control safety-related actuators (e.g., motor drives, valves) to protect personnel and equipment.
