3500/65 16-Channel Temperature Monitor

The Bently Nevada 3500/65 monitor provides 16 channels of temperature monitoring and accepts both resistance temperature detector (RTD) and isolated tip thermocouple (TC) 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.

FAQ of 3500/65

What is the 3500/65 16-Channel Temperature Monitor (145988-02 + 172109-01)?
A: The 3500/65 is a 16-channel temperature monitor used in the Bently Nevada 3500 Machinery Protection System. It accepts RTD (Resistance Temperature Detector) and isolated tip thermocouple (TC) inputs. The 172109-01 I/O module provides external terminations for field wiring via separate termination blocks and cables.

What is the power consumption?
A: 3 watts nominal.

Can the 3500/65 be used in TMR (Triple Modular Redundant) applications?
A: Yes. In TMR configurations, install three adjacent temperature monitors. The system uses two types of voting to ensure accurate operation and avoid single-point failures.
