The Bently Nevada 3500/60 Temperature Monitoring Module is part of the renowned 3500 Series machinery protection system. This module is specifically designed for temperature measurement and provides highly accurate, real-time monitoring for critical industrial assets. It works in conjunction with an I/O module (in this case, 133819-01), offering 6 input channels for both RTD (Resistance Temperature Detectors) and thermocouple types.
This module is ideal for applications where temperature rise can indicate bearing wear, winding damage, or early signs of mechanical failure.

Q1: What types of temperature sensors are supported?
A1: The module supports both RTD and thermocouple sensors. It’s configurable per channel, allowing for a mix of sensor types in one module.
Q2: Can I use all six channels simultaneously?
A2: Yes, each of the six channels is independent and can be configured for any supported sensor type.
Q3: Is the module hot-swappable?
A3: No. The module must be installed or removed with the rack power turned off to ensure proper function and safety.
Q4: What kind of alarms does the module support?
A4: Each channel supports two programmable alarms: Alert (warning level) and Danger (shutdown or critical action).
Q5: Can this module be used in high-vibration environments?
A5: Yes, it’s built to withstand industrial conditions including vibration, temperature fluctuation, and electrical noise.
Q6: Does it provide any isolation for inputs?
A6: The 133819-01 I/O module is a non-isolated version. Isolated options are available under different part numbers.
Q7: How does this module communicate with other system parts?
A7: It communicates over the 3500 rack’s backplane to the rack interface module, CPU, and display/relay modules.
Q8: What is the resolution of the temperature readings?
A8: The module offers high resolution, typically down to 0.1°C, depending on the sensor used.
Q9: Is the firmware upgradable?
A9: Firmware updates can only be performed through authorized service tools and require physical access.
Q10: Can this be used in safety-critical environments?
A10: Yes, when combined with proper system design, it can be part of SIL-compliant safety systems.
