Product Description

The 172109-01 is a high-performance Input/Output (I/O) interface specifically engineered for the Bently Nevada 3500/65 Temperature Monitor. This rear-mount module provides the physical termination and signal conditioning required to interface field-mounted temperature sensors with the 3500 series machinery protection rack. It is specifically designed to support Resistance Temperature Detectors (RTDs) and Isolated Tip Thermocouples (TCs), ensuring high-integrity data transmission for critical thermal monitoring of bearings, windings, and lube oil systems.

Technical Specifications

Specification Details
Channel Configuration Supports up to 16 independent temperature inputs
Compatible Sensor Types 3-wire RTDs (Pt100, Ni100) and Isolated Tip Thermocouples (Types J, K, E, T, S)
Signal Isolation High-grade galvanic isolation to prevent ground loops and electrical interference
Cold Junction Compensation Onboard precision compensation for thermocouple accuracy
Connection Interface High-density terminal headers for secure field wiring
Physical Dimensions 2.5 cm x 25.8 cm x 12.0 cm
Unit Weight 0.82 kg
Operating Temperature -30°C to +65°C (-22°F to +149°F)

Operational Integration

The 172109-01 installs directly into the rear of the 3500 rack, aligned with the 3500/65 monitor module. This architecture separates the sensitive processing electronics from the field wiring, enhancing system reliability. The "Isolated Tip" design is critical for industrial environments, as it allows the module to accurately read thermocouple signals even when the sensor tip is in contact with grounded machinery components, provided the sensor itself is internally isolated.

Engineering FAQ

Q: Can the 172109-01 be used with non-isolated (grounded) thermocouples?
A: No. Using grounded thermocouples with this specific I/O module will likely result in measurement errors or noise interference. For grounded thermocouple applications, a different I/O variant with higher channel-to-channel isolation is required.
