Manufacturing facilities have many processing areas that require layers of process protection to prevent unnecessary exposure to dangerous situations that may harm personnel or the environment. Most facilities have implemented Safety Instrumented Systems (SIS) in compliance with IEC 61511 to mitigate the exposure to such dangerous events.
When Safety Instrumented Functions (SIF) that make up the SIS are implemented, many of those loops will require a remote local indication of critical process variables for operators and technicians. The exida approved Functional Safety Series SLD Loop Display is IEC 61508 certified to use in these safety loops. The SLD was designed for critical loops and as such has a loop maintenance diode so if the SLD needs to be removed from the loop, the primary safety loop continues uninterrupted. With SIL 3 capability safety practitioners can install this loop indicator on any of their plant wide SIFs.
- exida approved to IEC 61508
- Worldwide hazardous area approvals
- Loop maintenance diode allows removal of SLD from loop with no dire consequences
