Product Short Description
Product Name: 3500/61 Temperature Monitor Module, 6-channel, with per-channel recorder output.
Product Introduction: Enhanced successor to 3500/60. Same 6-channel RTD/TC monitoring plus six independent 4–20 mA recorder outputs for DCS/SCADA/historian trending and predictive maintenance.
Technical Specifications:
- Channels: 6 independent inputs
Description
- Sensor Support: RTD (Pt100/Pt1000, 2/3/4-wire), TC (J/K/T/E/S/R/B)
- Recorder Output: 6 × 4–20 mA (one per channel)
- Input Impedance: ~10 MΩ per lead
- Alarm Accuracy: ±0.13 % of setpoint
- Setpoints: Alert + Danger, configurable hysteresis
- Power: 3500 backplane, ~9 W
- Operating Temp: -30 °C to +65 °C
- Weight: 0.91 kg
- Certifications: CSA NRTL, ATEX/IECEx options
Functional Features: Continuous analog out for every channel, mixed RTD/TC (non-isolated I/O), isolated TC version available, TMR support, EEPROM config.
Application Scenarios: Steam/gas turbine bearing temperature, generator winding thermal mapping, compressor cylinder temperature, refinery rotating equipment with DCS historian.
Structure & Material: Identical mechanical to 3500/60 with added recorder driver stage on PCB; aluminum faceplate, gold backplane fingers.
Working Principle: Same as 3500/60 plus internal DAC per channel drives 4–20 mA recorder signal proportional to measured temperature.
Installation Requirements: 3500 rack slot, I/O module 133819-02/133835-02, external TB 133827-02/133843-02, recorder loops to DCS analog input cards.
Usage Notes: Preferred replacement for 163179-01. Recorder outputs are sourced signals—do not parallel with other drivers. Use isolated I/O where ground loops exist.
