Safety Trip Alarm Video
Moore Industries has produced a video showing how its STA Safety Trip Alarm serves as a logic solver that goes beyond what users would expect from a standard alarm trip. The video shows how the STA can monitor potentially hazardous events as well as initiating emergency shutdown procedures or alerting personnel of unsafe process conditions. The video features a demonstration of how the STA serves as a single-loop logic solver in safety instrumented systems (SIS). It also shows how a third alarm monitors input or instrument faults such as a disconnected wire.
