Product Overview

The Triconex 3615E is a high-integrity Digital Output (DO) module for Tricon Triple Modular Redundant (TMR) safety systems. It provides 8 supervised 24 VDC output channels to control valves, motors, and emergency shutdown devices.

Featuring TMR isolation and 2oo3 voting logic, the module ensures safe operation even during a single component failure, making it ideal for Safety Instrumented Systems (SIS) in refineries, power plants, and other high-risk industries.

Technical Data

System Functions and Experience

• Load Supervision – Continuously monitors current flow to detect field device faults.

• Hot-Swappable – Can be replaced without interrupting process operation.

• High Availability – Built-in diagnostics help maintain >99.99% uptime.

• TMR Safety Logic – Two-out-of-three voting ensures safe control even if one channel fails.

Typical Applications

• Emergency Shutdown Systems (ESD) – Isolation valves, fire dampers

• Burner Management Systems (BMS) – Fuel gas shutoff valves

• Fire & Gas Systems (F&G) – Alarms and suppression systems

• Turbo-Machinery Protection – Trip solenoids for turbines and compressors

Frequently Asked Questions (FAQ)

Q1: What does the “E” suffix mean?
A1: Indicates an Enhanced version with improved diagnostics and thermal performance, meeting modern SIL 3 standards.

Q2: How does the module distinguish faults?
A2: Separate LEDs for FAULT (internal module) and LOAD (external wiring) allow quick identification of problem location.

Q3: Are external fuses required?
A3: Internal protection exists, but plant standards may require field fuses for additional safety.

Q4: Can it be used with 48 VDC or 125 VDC?
A4: No. Use 3617E for 48 VDC or 3613E for 120 VAC applications.
