TRICONEX 3009 (Enhanced Main Processor UMP · TMR Triple Modular Redundancy) Brand / Series: TRICONEX (a subsidiary of Schneider Electric), core controller for Tricon/Trident systems Model: 3009 (UMP, Enhanced Main Processor) Positioning: The "brain" of the system with TMR triple modular redundancy and SIL 3 rating, responsible for executing safety logic, redundancy management, I/O scheduling and external communication. ## I. Core Specifications (Official Standard Version) Processor: 32-bit high-speed microprocessor with TMR triple parallel operation Memory / Storage: Program Flash Memory: 16MB (Protected) Data Memory: 8MB Communication Interfaces: 2×TriBus (Redundant Backplane Bus for I/O connection) 2×RS-232 (Programming / Debugging) 1×Ethernet (Modbus TCP/IP) Safety Rating: SIL 3 (IEC 61508), TÜV Certified Power Consumption / Weight / Dimensions: ≤6W; Approx. 0.9kg; 114×30×185mm Operating Temperature: -40℃～+70℃ Redundancy / Hot Swap: 1:1 redundancy supported, module hot-swappable ## II. TMR Architecture & Functions Triple Voting: Three independent CPUs operate synchronously with 2-out-of-3 (2oo3) voting mechanism; single-point faults will not disrupt system operation. Real-time Diagnosis: Full-link self-inspection for CPU, memory, communication and power supply Automatic fault isolation, alarm triggering and redundancy switching Onboard LED Indicators: PASS/FAULT/ACTIVE status display System Capacity: Supports up to 96 I/O modules, compatible with 3503E/3604E/3704E/3805E and other models. ## III. Differences Between 3009 and 3501E (Main Controller) 3009 (UMP): Enhanced main controller with larger memory and stronger computing power, suitable for complex SIS logic, large-scale I/O and high-speed communication scenarios (v10/v11 systems). 3501E (MP): Standard main controller with basic configuration, applicable to small and medium-sized SIS and general logic applications (v9 and earlier systems). ## IV. Typical Applications SIS/ESD: Emergency Shutdown, Fire & Gas System (F&G), Burner Management System (BMS) Industries: High-risk scenarios including petrochemical, LNG, electric power, oil & gas, coal chemical and more Matching Modules: Power Module 8312, AI Modules 3481/3721/3704E, AO Module 3805E, DI Module 3503E, DO Module 3604E
