### 4. Functionality
The EX9018BL functions as a high-precision analog input module for temperature and analog signal acquisition. Each of its eight differential channels can measure thermocouple signals or low-level analog voltages. The module converts these analog signals into digital data using a 16-bit ADC and transmits the results via RS-485 serial communication.
Thermocouple Measurement Principle:
The module measures the Seebeck voltage generated by dissimilar metals at a junction. It employs Cold Junction Compensation (CJC) to correct for the reference junction temperature, ensuring accurate temperature readings across a wide range of thermocouple types.
Voltage and Current Measurement:
In addition to thermocouples, the EX9018BL can measure DC voltages and currents. Current measurement requires an external precision resistor (125 Ω, 0.1%) connected to the input terminals.
Applications:
- Industrial temperature monitoring and control
- Process automation and data acquisition systems
- Laboratory instrumentation
- Environmental and energy management systems
- Integration with PLCs, SCADA, and DCS systems via RS-485 networks
Compatibility:
