Bently Nevada 3500/60 (6‑Channel Temperature Monitor Module) – English Datasheet

Manufacturer: Bently Nevada (Baker Hughes)

Model: 3500/60 (Part No.: 163179‑01, etc.)

Type: 6‑channel temperature monitoring module (RTD/TC input, no recorder outputs)

Application: Turbine/generator bearing/winding temperature monitoring; part of 3500 TSI system (API 670 compliant).

General

• Channels: 6 independent, software‑configurable channels

• Input Types: RTD (Pt100/Pt1000) or Thermocouple (TC: J, K, E, T)

• Function: Conditions inputs, compares to user‑programmable Alert/Danger setpoints

• Difference from 3500/61: No analog recorder outputs (3500/61 has 6 recorder outputs)

• Power Consumption: 7 W nominal (from 3500 rack backplane)

Input Ranges & Accuracy

• RTD (Pt100): −40 °C to +260 °C; ±0.5 °C accuracy

• Thermocouples (TC):

  • Type E: −100 °C to +1000 °C

  • Type J: −18 °C to +760 °C

  • Type K: −18 °C to +1370 °C

  • Type T: −160 °C to +400 °C

  • Accuracy: ±1.0–1.5 °C (typical)

• Input Impedance: >10 MΩ per channel

• Scan Rate: 1 second per channel (update)

Alarm & Outputs

• Alarm Setpoints: 2 levels (Alert / Danger) per channel, programmable

• Relay Outputs: Via 3500 rack alarm relays (shared with system)

• Isolation Options:

  • Non‑isolated (mix RTD/TC)

  • TC‑isolated (250 Vdc channel‑to‑channel)

Environmental

• Operating Temp: −30 °C to +65 °C (−22 °F to +149 °F)

• Storage Temp: −40 °C to +85 °C (−40 °F to +185 °F)
