Safety trip alarm is SIL 2 and SIL 3 certified to IEC 61508

24 July 2012

The STA Safety Trip Alarm from Moore Industries has been certified by exida for Safety Instrumented Systems to IEC 61508:2010 for systematic integrity up to SIL 3 and for random integrity up to SIL 2.

This recent development means that that the STA is now approved for single use in Safety Instrumented Systems up to SIL 2 and in redundant architecture such as 1oo2 and 2oo3 up to SIL 3.

Approval from exida provides independent verification of the integrity of the STA and ensures that it meets the industry safety standards specified in IEC 61058: Parts 1, 2 and 3. As part of its certification of the STA, exida measured the effectiveness of the product development process to prevent systematic failures along with its strength at protecting against random failures.

The alarm comes with comprehensive safety data also certified by exida to determine its applicability to specific safety-related applications. In addition, reliability data from the unit can be used by engineers to design and verify each Safety Instrumented Function (SIF) in their system.

The STA provides an alternative method to backing up PLC or DCS soft alarms. It serves as a single-use safety logic solver that acts on hazardous process conditions, provides emergency shutdown and provides on/off control in Safety Instrumented Systems.
