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.
