Moore Industries-International, a provider of interface instruments for industrial process control, system integration and factory automation, published a white paper on a new generation of safety-certified single loop logic solvers for IEC 61508 requirements. The IEC 61508 standard focuses specifically on “Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems” and outlines the requirements International Electrotechnical Commission (IEC).

The paper, titled, “Safety Instrumented Systems: The ‘Logic’ of Single Loop Logic Solvers,” is a digital interactive publication available on the Moore Industries Web site. With a brief tutorial of Safety Instrumented Systems (SIS) and their related Safety Instrumented Functions (SIF), the white paper provides valuable background before delving into more complex topics including:
>> IEC 61508 Provision Guidelines
>> FMEDA Reports
>> Logic Solvers as Safety Trip Alarms and
>> Safety Integrity Level (SIL) Variations and Requirements.

Interactive elements includes pop-up “Selection Hints,” linking to data sheets and to helpful areas on Moore Industries’ Web site.
