I/O Module 135489-01 For BN 3500 Series Machinery Monitoring System in stock brand new

Overview

The 135489-01 is a high-performance I/O module in the Bently Nevada 3500/42M displacement seismic monitoring system. This module is primarily used to connect and monitor eddy current sensors and accelerometers located in hazardous areas. It effectively prevents unsafe energy from entering the field, providing a robust safety barrier for the entire industrial monitoring chain while ensuring monitoring accuracy.

Key characteristics

Machinery Protection Data: The hardware processes raw inputs to provide measurement variables including radial vibration, thrust position, eccentricity, velocity, and differential expansion.

High Measurement Accuracy: It delivers standard signal processing accuracy of ±0.33% full-scale typical (±1% maximum).

Internal Terminations: This specific model utilizes internal terminations. External termination blocks cannot be used with this part number

Common Questions Answered

Q: What sensors can the 135489-01 connect to?
A: The 135489-01 is a dedicated 4-channel Prox/Acceleration version. It supports:
Proximity probes (shaft vibration, shaft displacement, Keyphasor, and gap measurement)
Acceleration sensors (casing vibration measurement)

Q: Can the 135489-01 board connect to an external terminal block?
A: No. Because its model definition is "Internal Terminations," field signal wires must connect directly to the board's built-in terminals. It does not support or require an external terminal block.

Q: Does the 135489-01 board conform to API 670 standards?
A: Yes. The Bentley 3500 system and this I/O board fully comply with the API 670 machinery protection standard and can be used in protection and interlocking circuits with SIL safety level requirements.

Q: What types of products do you specialize in?
A: We specialize in industrial automation components, including PLC modules, sensors, servo drives, and discontinued parts from major brands like Siemens, Allen-Bradley, and Bently Nevada.
