Using the STA as a Single Loop Logic Solver

Using the STA as a Single Loop Logic Solver (SLLS)

Problem: We need to implement several temperature related Safety Instrumented Functions (SIF) in multiple areas throughout our plant. The SIF needs to be IEC 61511 compliant and involves a Logic Solver, Sensor and Final Control Element.

Solution: The SIL 2/3-capable STA Safety Trip Alarm can be used as an effective yet affordable Single Loop Logic Solver to slam shut or open a valve to mitigate a dangerous process condition. Additionally, the STA can retransmit the temperature signal to a Basic Process Control System for additional monitoring or control purposes.
