Actual Cases

1. Chemical Plant Safety System
   In a large chemical plant, the TRICONEX 4211 was installed as part of the Safety Instrumented System for a reactor. It continuously monitored the temperature and pressure of the reactor through digital inputs. One day, the temperature started to rise abnormally. The TRICONEX 4211 quickly detected this change and sent a signal through the digital output to shut down the reactor and activate the emergency cooling system. This timely action prevented a potential explosion and protected the plant and its workers.
2. Oil Rig Emergency Shutdown
   On an offshore oil rig, the TRICONEX 4211 was used in the Emergency Shutdown System. When a gas leak was detected by the connected gas sensors, the module immediately initiated an emergency shutdown of the oil production process. It also activated the ventilation system to disperse the gas and sent an alarm signal to the control room. This helped to avoid a major accident and minimize the environmental impact.
