Description
Product Overview
The Bently Nevada 3500/60 with 133843-01 TC Isolated I/O Module is designed for high-integrity thermocouple signal acquisition within the 3500 machinery protection architecture. It is engineered for environments where electrical interference, long cable runs, and ground potential differences can degrade temperature measurement accuracy.
This module provides electrically isolated thermocouple channels to ensure stable and repeatable temperature data for critical rotating equipment such as turbines, compressors, and driven machinery.
Functional Description
The module interfaces directly with standard thermocouple sensors and performs signal conditioning, linearization, and conversion into engineering units for the 3500 rack system.
Key functional roles include:
-
Multi-channel thermocouple signal acquisition
-
Channel-to-channel electrical isolation to reduce noise coupling
-
Integration with 3500 rack monitoring and alarm logic
-
Stable operation in high EMI industrial environments
