Bently Nevada Isolated +4 to +20 mA I/O Module 136483-01

136483-01

|Rated 5.0

The 136483-01 module continuously compares monitored parameters against configured alarm setpoints to trigger alarms for machinery protection. It provides essential machine information for both operations and maintenance personnel.

When used in a Triple Modular Redundant (TMR) configuration, the Process Variable Monitors must be installed adjacent to each other in groups of three. This configuration utilizes two types of voting to ensure accurate operation and prevent the loss of machinery protection due to single-point failures.

FAQ
1. How does the TMR configuration work with the Process Variable Monitor?
In a Triple Modular Redundant (TMR) configuration, three Process Variable Monitors must be installed adjacent to each other. This setup ensures accurate monitoring by using dual voting mechanisms to prevent errors due to single-point failures, ensuring reliable machinery protection.
2. What type of voting is employed in the TMR configuration?
The TMR configuration employs two types of voting mechanisms to ensure redundancy and accuracy in operation. This is designed to avoid failure in case one of the modules encounters a fault.
3. Can I use the 136483-01 in non-TMR systems?
Yes, although it is primarily designed for TMR configurations, the 136483-01 can also be used in non-TMR systems, but the benefits of redundancy and failover provided by TMR will not be available.
