Moore Industries has produced a new video showing how its STA Safety Trip Alarm serves as a logic solver that will monitor potentially hazardous events and initiate emergency shutdown procedures.
This video is available through the Moore Industries website at http://www.miinet.com/safetyseries
The STA performs some of the same functions as expensive safety PLCs, but is more affordable and easier to program. The process alarm trips and analog outputs are user configurable via front-panel push buttons.
Configurations can be downloaded to multiple STA units with a free software utility program. It has been subjected to extensive testing by TUV and Exida, and has been approved for IEC 61508 and 61511 compliance – including single use in Safety Instrumented Systems up to SIL 2 and firmware suitable for use in a SIL 3 system.
