PL (Performance Level) is defined by ISO 13849-1 and is common in machinery, while SIL (Safety Integrity Level) is defined by IEC 62061 and IEC 61508. Both quantify the probability of dangerous failure, but use different calculation methodologies.
Machine Safety Components Component Intelligence
Engineered protection for high-risk industrial environments.
What are Machine Safety Components components?
Machine safety components are critical for risk mitigation in automated systems. Selection hinges on the required Performance Level (PL) or Safety Integrity Level (SIL), environmental ingress protection, and the specific failure-mode diagnostic requirements of your safety circuit.
How to Choose Machine Safety Components Components
Selecting safety hardware requires strict adherence to risk assessment outcomes. Focus on these technical pillars:
Safety Integrity Level (SIL/PL)
Match the component's rated PL or SIL to the risk assessment of the machine to ensure adequate fault tolerance.
Response Time
Calculate the total system response time, including sensor detection and relay de-energization, to determine safe distance.
Environmental Rating
Verify IP ratings and operating temperature ranges to ensure reliability in harsh industrial or wash-down environments.
Diagnostic Coverage
Prioritize devices with built-in self-diagnostics to detect internal faults before they lead to a dangerous failure.
Interoperability
Ensure safety controllers and sensors share compatible communication protocols and wiring standards for seamless integration.
