TRICONEX 3604E Triple Modular Redundancy (TMR) safety controller

I. Core Functional Features

1. Safety Architecture and Level
   • Adopts Triconex's iconic Triple Modular Redundancy (TMR) design. It processes data in parallel through three independent and synchronized processor channels, combined with a majority voting mechanism (2oo3). This design can automatically shield single-channel faults, ensuring the system still operates reliably even when hardware failures occur.
   • Meets the world's highest safety standards: Certified SIL 3 (Safety Integrity Level 3) by TÜV, and complies with standards such as IEC 61508 (general safety standard), IEC 61511 (process industry safety standard), and ISA 84.00.01. It is suitable for critical safety control scenarios (e.g., emergency shutdown, fire protection, pressure relief interlock).
2. Control and Computing Capabilities
   • Supports complex safety logic programming and is compatible with Triconex's dedicated programming software (e.g., Triconex Engineering Studio). It enables multiple programming methods including Ladder Diagram (LD), Function Block Diagram (FBD), and Structured Text (ST) to meet interlock logic requirements of different processes.
   • Features high-speed logic computing capability, with a typical scan cycle as low as milliseconds. This ensures rapid response to on-site emergency signals (e.g., overpressure, overtemperature, emergency stop commands) and prevents the escalation of hazardous events.

The company has multiple main brands, and if you have other brand requirements, you can also send them to customer service for inquiry.
