Description
The Bently Nevada 126632-01 TMR I/O Module is a core component of the 3500 Series Mechanical Protection System, designed for high-reliability monitoring of bearings and rotating machinery. As part of the 3500/42M Triple Modular Redundancy (TMR) monitor, it accepts signals from 1 to 4 proximity, velocity, or acceleration transducers and converts them into precise data for machinery protection. Typical power consumption is 7.7 watts, and the module provides robust input and output impedance (10 kΩ input, 550 Ω output) with a dedicated -24 Vdc transducer power supply.

Unlike the standard 3500/42 module, the 126632-01 employs TMR architecture, offering extremely high fault tolerance and reliability for applications where downtime is unacceptable. It features external terminations and requires an External Termination Block (ET Block), allowing easier wiring management and simplified installation compared to internal termination versions. This setup enhances maintainability while ensuring consistent signal integrity.

The Bently Nevada 126632-01 supports a wide range of monitoring functions, including radial vibration, thrust position, differential expansion, eccentricity, REBAM*, acceleration, velocity, shaft absolute, and circular acceptance region. Each of the four channels can be individually programmed via 3500 Rack Configuration Software to meet specific measurement and alarm requirements, providing flexibility for complex machinery monitoring tasks.

Engineered for industrial environments, the 126632-01 operates over a wide temperature range (-30°C to +65°C / -22°F to +150°F) and can be stored safely from -40°C to +85°C (-40°F to +185°F), withstanding up to 95% non-condensing humidity. Its external terminations and TMR architecture make the 126632-01 TMR I/O Module particularly advantageous for critical machinery protection where maximum reliability and ease of maintenance are essential.
