Working Principle: The module receives temperature signals from RTD or thermocouple sensors through internal terminations. For RTD inputs, the module provides constant current excitation, measures resistance changes, and converts to temperature values. For thermocouple inputs, the module measures thermoelectric potential and converts to temperature values. Internal circuits amplify, linearize, and temperature-compensate the signals, then transfer processed data to the main monitoring module for alarm determination and display.
Installation Requirements:
- Install in rear slot corresponding to 3500/60 main module
- RTD sensors must use 3-wire or 4-wire connection to eliminate lead resistance effects
- Thermocouple sensors must use compensation wire connections to ensure measurement accuracy
- Ensure sensor wiring is correct with proper polarity
- Maintain appropriate spacing from high-voltage power cables
Use Precautions:
- This non-isolated module is not suitable for applications requiring channel-to-channel isolation
- For applications requiring 250 VDC channel-to-channel isolation, select the thermocouple isolated version
- Global industrial standard and recommended material is platinum RTD with alpha=0.00385
- Using external safety barriers can extend low temperature measurement range to -50°C
- When used in TMR configuration, temperature monitors must be installed in groups of three side by side
- Inspect sensor wiring status regularly to ensure reliable connections
- Replace module only with identical model
