Many mining locations require layers of process protection to prevent unnecessary exposure to dangerous situations that may harm personnel or the environment, like gas exposure. Most mining operations have implemented Safety Instrumented Systems (SIS) in compliance with IEC 61511 to mitigate the exposure to such dangerous events.
When required to add layers of protection at the mine site, consider the STA Functional Safety Trip Alarm as your Safety Instrumented System logic solver when a dangerous condition occurs. The STA is simple to program and has an auxiliary analog output for retransmission to the local RTU. The STA is SIL 2/3 capable, approved by exida and rated for installation in Class I Div 2/Zone 2.
