      Information

      Overview Manuals Common Applications Product Precautions
      The 3500/65 145988-02 172109-01  is a hardware combination specifically designed for temperature monitoring.145988-02 is the main module of this module.172109-01 is the matching I/O module. 
        • Supports multiple industry standard sensors
        • A single module can support 16 channels of temperature input
        • Capable of monitoring the temperature difference between two channels
      The Bently Nevada 3500/65 monitor provides 16 channels of temperature monitoring and accepts both resistance temperature detector and isolated tip thermocouple temperature inputs. The monitor conditions these inputs and compares them against user-programmable alarm setpoints. The monitor is programmed using the 3500 Rack Configuration Software. You can configure the 16-Channel Temperature Monitor to accept isolated tip thermocouples, 3-wire RTD, 4-wire RTD, or a combination of TC and RTD inputs. In Triple Modular Redundant configurations, you must install temperature monitors in groups of 3 adjacent monitors. In this configuration the monitor uses 2 types of voting to ensure accurate operation and to avoid single point failures.

       When using the Bently Nevada 3500/65 temperature monitor combination, ensure that the hardware suffixes of the main and I/O modules match strictly, and accurately define the sensor type (RTD or Thermocouple) for each channel in the configuration software. It is crucial to prioritize the accuracy of Cold Junction Compensation on the I/O module and periodically check the tightness and shield grounding of external terminal wiring to prevent temperature reading drifts or nuisance alarms caused by electromagnetic interference or contact resistance.
