Description

The 172109-01 is a Bently Nevada 3500/65 RTD/Isolated Tip TC I/O Module designed for external terminations. It provides 16 channels of temperature monitoring within the 3500 Machinery Condition Monitoring System. This module conditions signals from resistance temperature detectors (RTD) and isolated tip thermocouples (TC), comparing them against user-programmable alarm setpoints to ensure machinery safety and reliability.

Features

• Provides 16 channels of temperature monitoring.
• Supports 3-wire RTD, 4-wire RTD, and isolated tip thermocouple inputs.
• Configurable via 3500 Rack Configuration Software with no field calibration required.
• Supports Triple Modular Redundant (TMR) configurations when installed in groups of three adjacent monitors.
• External termination design allows for flexible field wiring via external terminal blocks.

Applications

• Turbines: Monitoring bearing, casing, and exhaust temperatures for steam and gas turbines.
• Compressors: Monitoring cylinder head, lubricant, and bearing temperatures for centrifugal and reciprocating compressors.
• Motors & Generators: Stator winding and bearing temperature monitoring for large rotating equipment.
• Pumps: Detecting seal and bearing frictional heat in high-pressure pump applications.
• Gearboxes: Monitoring thermal states to detect gear mesh or lubrication failures.

Installation Guidelines

• Slot Alignment: The 172109-01 must be installed in the rear slot of the 3500 rack, directly behind the corresponding 3500/65 main monitor module.
• Insertion: Slide the module into the guide rails and press firmly to seat the connector into the rack backplane. Secure using the two captive thumb screws on the faceplate.
• Firmware Compatibility: When replacing older I/O modules with newer revisions, ensure the monitor firmware is upgraded to the latest version before installation to prevent I/O Module Mismatch errors.
• TMR Setup: For Triple Modular Redundant configurations, install modules in groups of three adjacent slots.
• Handling: Use standard ESD precautions when handling electronic modules.

Compliance and Certifications

The 172109-01 complies with FCC Rules Part 15, EMC Directive 2014/30/EU, LV Directive 2014/35/EU, and RoHS Directive 2011/65/EU. It is certified for hazardous areas including CSA/NRTL/C Class I, Zone 2, and ATEX/IECEx II 3G Ex nA nC ic IIC T4 Gc.
