The 172109-01 is a communication gateway module designed specifically for the 3500 monitoring system, often referred to as the 3500/92 communication gateway module.
16-Channel Flexible Inputs
External Termination Architecture
Signal Conditioning & CJC
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. In Triple Modular Redundant (TMR) 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.

Thermal Power Generation
Monitors steam turbine and generator bearing temperatures to prevent catastrophic oil film breakdown.
Oil & Gas
Secures the gas turbines and centrifugal pumps at remote pipeline compressor stations.
Hydroelectric Power
Monitors the massive thrust and guide bearings of vertical hydro-generator units.
Nuclear Power
Oversees the winding and bearing temperatures of massive reactor coolant pumps (RCP).
Steel Metallurgy
Protects the high-power blast furnace blowers and oxygen plant turbo-compressors.
Pulp & Paper
Tracks the operational temperature of large boiler ID (Induced Draft) and FD (Forced Draft) fans.
When deploying the 172109-01 module, engineers must utilize the dedicated 134544 cable with proper shield grounding to eliminate ambient noise. It is critical that programmed transducer parameters exactly match the field RTDs or thermocouples to avoid "I/O Module Mismatch" faults. Technicians must also verify that onboard Cold Junction Compensation and loop resistance are fully balanced post-installation. Lastly, while the 3500 chassis supports Removal and Insertion Under Power, hot-swapping the 172109-01 requires extreme caution, as it temporarily suppresses active safety interlocks across all 16 channels.
It identifies an Isolated Tip Thermocouple (TC) I/O Module designed for temperature measurement and signal processing in industrial systems.
How many input channels does the 172109-01 provide?
It provides 16 highly dense, fully independent input channels that can be individually programmed and configured using the 3500 Rack Configuration Software.
Which systems commonly use the 172109-01 module?
It is used in turbines, compressors, boilers, and industrial machinery requiring precise temperature monitoring.
Does the 172109-01 module support Triple Modular Redundancy (TMR)?
Yes, it fully supports Triple Modular Redundancy (TMR) configurations.
