About Woodward ProTech TMR

The Woodward MicroNet TMR (Triple Modular Redundant) and ProTech safety systems provide the highest level of turbine protection and safety shutdown capability. Using 5501 and 5500 series modules, these systems employ triple redundant architecture with two-out-of-three voting logic for maximum reliability. They are designed for SIL 2/3 safety applications and are used as primary protection systems on critical gas turbines and compressor drives worldwide. BDB Turbine Parts supplies TMR modules for both new installations and maintenance of existing systems.

Specifications: Module series: 5501/5500 | Architecture: Triple Modular Redundant (TMR) | Safety: SIL 2/3 certified | Voting: 2-out-of-3

Applications: Gas turbine overspeed protection, emergency shutdown systems, compressor surge protection, fire & gas detection, critical safety interlocks

Frequently Asked Questions - Woodward ProTech TMR

What is Triple Modular Redundancy (TMR)?
TMR uses three independent processing channels that continuously compare results. If one channel disagrees, the other two override it (2-out-of-3 voting), ensuring safe operation even with a single failure.
Which 5501/5500 modules are most critical?
Critical modules include 5501-470 (TMR CPU), 5501-380 (Analog Input), 5500-318 (Digital Output), 5501-427 (Power Supply), and 5500-385 (Communication Module).
What SIL rating does the MicroNet TMR achieve?
The MicroNet TMR platform is certified for SIL 2 and SIL 3 applications per IEC 61508/61511, making it suitable for the most critical safety functions in turbine and compressor protection.
Can TMR modules be tested without shutting down?
Yes, the TMR architecture allows online testing of individual channels without affecting plant operation. One channel can be taken offline for testing while the remaining two maintain full protection.
Do you offer urgent delivery for TMR safety modules?
Yes, we understand the critical nature of safety system components. We offer expedited shipping and maintain emergency stock of the most commonly needed TMR modules.
