The TRICONEX TRICON 3504E is a high-density digital input module used in safety instrumented systems (SIS) like chemical plants, oil rigs, and nuclear facilities.

• High density: It has 48 digital inputs that can be used to monitor a variety of sensors.
• Triple modular redundancy (TMR): This is a fault-tolerant design where critical components are triplicated. If one channel fails, the other two can still function correctly.
