Structural Features: The unit features a compact 35mm width. The front panel includes a removable terminal block for sensor wiring.
Working Principle: The unit excites the resistance thermometer with a constant current, measures the voltage drop, and calculates the temperature based on the resistance-temperature characteristic. The signal is isolated and converted to digital data for the CPU.
Installation Requirements:
- Mount on CS1 series CPU rack or expansion rack.
- Use 3-wire or 4-wire connection for Pt100 sensors to minimize lead resistance errors.
- Ensure proper grounding.
Usage Notes:
- Verify the sensor type (Pt100 vs JPt100) matches the configuration.
- Do not apply voltage to the input terminals.
- Ensure the wiring is secure to prevent measurement errors.
