Quick Detail

Description

The 172103-01 RTD/Isolated Tip TC I/O Module is part of the Bently Nevada 3500/65 Series 16-Channel Temperature Monitor system. The 172103-01 accepts 16 temperature inputs from both resistance temperature detectors (3-wire or 4-wire RTDs) and isolated tip thermocouples (TC). Each input is conditioned and continuously compared against user-programmable alarm setpoints. Configured using the 3500 Rack Configuration Software, the 172103-01 supports Triple Modular Redundant (TMR) installations with dual voting logic to monitor and detect faults across all channels. The module occupies 1 full-height rear slot and enables precise temperature monitoring for critical machinery. The 172103-01 ensures consistent signal evaluation from RTD or TC inputs and integrates seamlessly with 3500/65 systems to automate temperature monitoring and alarm response.

Applications

Monitor 16 Temperature Channels on Critical Machinery
The 172103-01 manages 16 channels of temperature inputs from RTDs or isolated tip thermocouples (TC). Each channel measures temperature across -40°C to +100°C, and the monitor compares these readings to user-programmable alarm setpoints, providing precise monitoring for turbines, compressors, and pumps.

Automate Alarm Responses Using 3500 Rack Configuration Software
The 172103-01 triggers alarms when any of the 16 channels exceeds setpoints. With a ±1% full-scale accuracy for RTD and TC inputs, operators can automate immediate responses, minimizing overheating risks and protecting industrial assets.

Integrate into Triple Modular Redundant (TMR) Systems
The 172103-01 supports TMR installation with dual voting logic, ensuring fault-tolerant monitoring. This setup compares three adjacent modules’ outputs, validating alarms only when confirmed across modules, reducing false triggers for all 16 channels.

Combine RTD and TC Inputs in a Single Module
With support for 3-wire RTDs, 4-wire RTDs, and isolated tip TCs, the 172103-01 allows mixed-sensor environments to be consolidated into one module. This flexibility reduces the need for additional hardware and maintains a single 1 full-height rear slot footprint per module.

Specifications

Competitive Advantage

High-Channel Density
The 172103-01 monitors 16 temperature channels per module, reducing rack space usage while covering extensive machinery points. With 16 channels and 1 full-height rear slot, operators gain efficient, space-saving deployment.

Precision Alarm Monitoring
The 172103-01 evaluates inputs against user-programmable alarm thresholds with ±1% full-scale accuracy. Each channel can be configured individually, allowing precise alarm detection on all 16 channels simultaneously.

Rapid Integration with 3500/65 Systems
The 172103-01 is fully compatible with 3500 Rack Configuration Software, enabling fast setup and commissioning. Parameter programming for all 16 channels can be done in minutes, optimizing automation workflows.

TMR Fault Detection with Dual Voting
The 172103-01’s dual voting logic compares data from three adjacent modules in a TMR configuration. Any channel deviation is flagged only after two votes confirm it, providing fault-tolerant operation across all 16 monitored channels.

Flexible Input Compatibility
The 172103-01 supports RTD (3-wire/4-wire) and isolated tip TC inputs, or a combination of both. This allows standardization across machinery with mixed sensor types, reducing spare parts complexity and maintaining the 1-slot footprint per module.
