Bently Nevada 136711-02 3500/61 RTD/TC I/O Module with Internal Barriers and Internal Terminations

Description

The Bently Nevada 136711-02 is a non-isolated RTD/TC I/O module with internal barriers and internal terminations designed for processing temperature transducer inputs within the 3500 Machinery Protection System. Installed in a full-height rear slot directly behind the 3500/61 Temperature Monitor main module, it accepts input signals from up to six Resistance Temperature Detector (RTD) or Thermocouple (TC) transducers. The 136711-02 channels conditioned signals and +4 to +20 mA proportional recorder outputs through integrated internal barriers to support intrinsically safe machinery monitoring applications in industrial environments.

Features

• Provides internal zener barriers and internal termination wiring connectors for six input channels
• Interface options configurable for 3-wire RTD, 4-wire RTD, and Thermocouple transducers
• Integrates directly behind the 3500/61 Temperature Monitor via the 3500 system backplane
• Routes +4 to +20 mA proportional recorder outputs for each individual channel

Applications

• Bearing temperature monitoring in rotating machinery such as turbines, compressors, and pumps
• Process temperature measurement using RTD and TC transducers in hazardous location areas
• Machinery protection and condition monitoring within the 3500 system architecture

Installation Guidelines

• Install the I/O module in a single full-height rear slot positioned directly behind the corresponding 3500/61 Temperature Monitor module.
• Secure wiring connections to the green and blue internal termination connector headers according to transducer type wiring configurations.
• Ensure operating ambient temperatures remain within the designated limit of 0 degC to +65 degC when internal barriers are active.
