Moore Industries SIL 3 Capable STA Safety Trip Alarm Certified by exida®

Moore Industries SIL 3 Capable STA Safety Trip Alarm Certified by exida®

Part of the Moore Industries FS FUNCTIONAL SAFETY SERIES, the exida® certified SIL 2 and SIL 3 capable STA Safety Trip Alarm performs as a logic solver and acts on potentially hazardous process conditions; warns of unwanted process conditions; provides emergency shutdown; or provides on/off control in Safety Instrumented Systems (SIS) and traditional alarm trip applications. The STA has a systematic integrity up to SIL 3 and random integrity up to SIL 2 which allows the STA to be used in a redundant architecture (1oo2, 2oo3, etc.) up to SIL 3.

EHELP: Using the STA for a high temperature Safety Instrumented Function

EHELP: Using the STA for a high temperature Safety Instrumented Function

Q. Currently we monitor the temperature level in our oven with a thermocouple and let our PLC control the oven. We now need to implement a high temperature Safety Instrumented Function (SIF).  Do we need duplicate temperature sensors and do you have a Functional Safety device that can provide oven shutdown capability on high temperature?

Moore Industries Spotlight: Alarms

Moore Industries Spotlight: Alarms

Moore Industries has been designing and manufacturing alarms since 1968 (read our recent blog on our presence in the process instrumentation industry: Moore Industries: A History of Innovation and Safety). Our alarms have evolved from simple high/low logic devices to highly flexible PC-programmable devices extending into IEC 61508 Functional Safety and Intrinsically-Safe (IS) methods of protection. To learn about Moore Industries’ alarm products, visit our Limit Alarm Trips and Switches Product Information Page.

STA Aids in Functional Safety Coal Gas Extraction Application Down Under

STA Aids in Functional Safety Coal Gas Extraction Application Down Under

Moore Industries-Pacific recently sold 221 STA Safety Trip Alarms to be used in a Functional Safety coal gas extraction application in Australia. A Coal Seam Gas exploration company with hundreds of sites in Queensland has production wells with up to 10 inputs controlled locally by Remote Terminal Units (RTUs). The STA will be implemented as part of their independent Protection System with a level alarm on each wellhead separator. Larger volume production wells may need up to four separators per RTU panel.
