        Features:

        • RTD and Isolated Tip Thermocouple Temperature Monitoring for 3500 Rack Systems
        • 16-Channel Temperature Input Conditioning with User-Programmable Alarm Setpointst
        • Compatible with Triple Modular Redundant Configurations and Standard 3500 Monitors
        The Bently Nevada 172103-01 3500/65 RTD/Isolated Tip TC I/O Module with Internal Terminations serves as the dedicated temperature monitoring interface within a 3500 rack, providing precise temperature measurement capabilities across 16 independent channels. The 172103-01 accepts both resistance temperature detector (RTD) and isolated tip thermocouple (TC) temperature inputs, conditions these signals, and compares them against user-programmable alarm setpoints to enable early detection of thermal anomalies. The 172103-01 is configured using the 3500 Rack Configuration Software, allowing operators to set up the module to accept isolated tip thermocouples, 3-wire RTD, 4-wire RTD, or a combination of TC and RTD inputs depending on the specific application requirements.

        The 172103-01 provides essential temperature monitoring functions critical to the protection of rotating machinery assets, and is a vital component of the overall monitoring path, directly influencing the accuracy and reliability of thermal protection strategies. One 172103-01 module occupies a standard slot within the 3500 rack and integrates seamlessly with the rack backplane for signal processing and communication with other system modules.

        For Triple Modular Redundant (TMR) applications, the 172103-01 must be installed in groups of 3 adjacent monitors. In addition to standard single-module operation, the TMR configuration performs dual voting mechanisms to ensure accurate operation and prevent single-point failures. The 172103-01 TMR setup continually monitors the health of all three modules through internal voting logic. If the system detects that one 172103-01 module is providing inconsistent or out-of-tolerance readings compared to the other two, it will automatically disregard the faulty channel and place an event in the System Event List, maintaining continuous and reliable temperature monitoring.

        The 172103-01 Bently Nevada RTD/Isolated Tip TC I/O Module with Internal Terminations may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The Bently Nevada 172103-01 is a high-density I/O module specifically designed for the 3500/65 16-Channel Temperature Monitor. This module features Internal Terminations, allowing for direct wiring connections at the rear of the 3500 rack. It is engineered to interface with both Resistance Temperature Detectors (RTDs) and isolated tip Thermocouples (TCs), facilitating the integration of 16 independent temperature channels into the machinery protection system.

        This 172103-01 module is purpose-built to handle the challenges of high-density temperature monitoring in critical rotating machinery, such as large steam turbines or industrial compressors. By providing 16 channels in a single slot, the 172103-01 solves the problem of limited rack space and complex external wiring, eliminating the need for separate external terminal blocks and reducing the overall footprint of the protection system.

        In demanding environments, the 172103-01 is designed to address the issue of signal integrity and common-mode noise when monitoring bearing temperatures or motor windings. It solves the problem of ground loops and electrical interference specifically by supporting isolated tip thermocouples and providing filtered inputs. This ensures that the 3500/65 monitor receives accurate data for comparing against user-programmable alarm setpoints, preventing false trips or undetected overheating.

        Furthermore, the 172103-01 supports Triple Modular Redundant (TMR) configurations, where it is installed in groups of three to ensure continuous operation. This specific setup for the 172103-01 is designed to handle critical failure risks in high-availability processes, solving the problem of single-point failures through hardware voting. This makes the 172103-01 an essential component for industries where unplanned downtime must be strictly avoided.
