172109-01 | Bently Nevada | Isolated Tip TC I/O Module

### Product Description
The 172109-01 is a single-channel isolated thermocouple input module designed for the Bently Nevada 3500 machinery protection system. It provides galvanic isolation between field wiring and the rack backplane to prevent ground loops and noise interference.
Moreover, it conditions and digitizes millivolt-level thermocouple signals with cold-junction compensation for accurate temperature measurement in harsh industrial environments. Therefore, it supports continuous monitoring of bearing, casing, and exhaust temperatures on rotating machinery. In addition, its isolation rating and diagnostic capabilities enhance system reliability during critical operations.

### Technical Specifications

### Typical Applications
– Monitoring turbine bearing metal temperatures in power generation facilities
– Measuring compressor discharge and casing temperatures in oil and gas processing
– Tracking gearbox and motor winding temperatures in industrial drive systems
– Providing isolated thermocouple inputs for critical rotating equipment in refineries and chemical plants

### FAQ
What thermocouple types does the 172109-01 support?
It supports J, K, T, E, R, S, B, N, and C thermocouple types via software configuration.

Does the module require external power?
No—it receives operating power from the 3500 rack backplane; no separate field power supply is needed.

Is cold-junction compensation built-in?
Yes—integrated cold-junction compensation is performed automatically at the module’s terminal block.

Can multiple 172109-01 modules be installed in one 3500 rack?
Yes—up to eight 172109-01 modules may be installed per 3500 rack, subject to power and slot constraints.

What is the isolation voltage rating?
The module provides 1500 V AC channel-to-backplane isolation and 500 V AC channel-to-channel isolation.
