Product Overview
The Triconex 3003-EMPII is the Enhanced Main Processor for Tricon Safety Systems, providing fault-tolerant control for high-hazard industrial environments.
With Triple Modular Redundancy (TMR) and the TriBus communication system, it ensures safe and continuous operation for Emergency Shutdown (ESD), Fire & Gas (F&G), Burner Management (BMS), and High Integrity Pressure Protection (HIPPS) applications.
The "Enhanced" designation provides faster logic execution and improved diagnostic coverage compared to legacy 3003 processors.

High Integrity Pressure Protection (HIPPS) – Prevents over-pressurization in pipelines.
Frequently Asked Questions (FAQ)
Q1: What is the role of the TriBus?
A1: TriBus links the three processors, allowing synchronization and 2-out-of-3 voting to ensure only valid logic is executed.
Q2: Is the 3003-EMPII compatible with all Tricon chassis?
A2: It is designed for the Main Chassis, and TMR requires three 3003-EMPII modules installed in designated slots.
Q3: Can legacy 3003 modules be upgraded to EMPII?
A3: Yes, but check TriStation 1131 software for firmware and configuration compatibility.
Q4: How does the module handle power failure?
A4: Flash PROM stores the program, and battery-backed SRAM preserves retentive variables, enabling a safe restart after power restoration.
