Description
Description
The Bently Nevada 133835-01 is an Isolated Thermocouple (TC) Temperature I/O Module designed for use within the 3500 machinery protection system. This module provides high-precision temperature monitoring for critical rotating machinery, such as turbines, compressors, and large motors. By utilizing isolated input channels, the 133835-01 ensures signal integrity and minimizes common-mode noise interference, which is essential for accurate bearing and stator temperature tracking. This I/O module is engineered to work in conjunction with the 3500/60 monitor module and supports external termination blocks, facilitating efficient field wiring and simplified maintenance procedures.
Features
-
Isolated Inputs: Each thermocouple channel is electrically isolated to prevent ground loops and signal degradation.
-
External Termination: Designed for use with external termination blocks, allowing for easier cable management and field maintenance outside the main rack.
-
System Integration: Fully compatible with the Bently Nevada 3500 rack series, supporting redundant power and communication configurations.
-
Programmable Alarms: Integrates with 3500 rack configuration software to enable user-defined Alert and Danger setpoints for proactive machinery protection.
-
Robust Design: Built for harsh industrial environments with a wide operating temperature range.
Applications
- Bearing temperature monitoring in centrifugal compressors.
- Stator winding temperature tracking in large electric motors and generators.
- General-purpose thermocouple monitoring for industrial rotating equipment.
- Critical machinery protection systems requiring high-reliability signal isolation.

Installation Guidelines
-
ESD Protection: Always use a properly grounded anti-static wrist strap when handling the module to prevent damage to sensitive internal electronics.
-
Rack Seating: Ensure the module is fully seated in the designated 3500 rack slot and that the front panel screws are tightened to maintain proper grounding and EMI shielding.
-
Power Status: Ensure the rack power is managed according to site safety procedures before inserting or removing any I/O module.
-
Wiring: Use shielded thermocouple extension wire to maintain signal integrity. Route signal cables away from high-voltage power lines and high-EMI sources to prevent noise injection.
-
External Termination: Ensure the external termination block is correctly wired and securely mounted before connecting to the I/O module.
FAQ
Q: Does this module include the terminal block?
A: The 133835-01 is the I/O module itself. External termination blocks are typically ordered separately depending on your specific wiring requirements.
Q: Is this module compatible with all 3500 racks?
A: Yes, it is designed for standard Bently Nevada 3500 series racks. Ensure your rack configuration software is updated to support the 3500/60 module series.
