Detailed content

  • Input Signals:​ 4–20 mA DC / 0–20 mA DC / 0–10 V DC / ±10 V DC (configurable)
  • Resolution:​ 13-bit (8192 levels)
  • Input Impedance:​ 250 Ω (current) / 1 MΩ (voltage)
  • Conversion Rate:​ ≤ 10 ms per channel (typical)
  • Accuracy:​ ± 0.1 % full scale (typical)
  • Channel Isolation:​ Inter-channel isolated, 250 V DC isolation voltage

  • Power Consumption:​ ≤ 1.5 W (typical)
  • CMRR:​ ≥ 90 dB @ 50 Hz
Material & Construction:
  • PCB:​ FR-4 multi-layer surface-mount board
  • Connectors:​ Gold-plated spring contacts
  • Housing:​ Metal shielded enclosure
  • A/D Converter:​ High-precision Σ-Δ ADC
  • Form Factor:​ Standard PCB card, approx. 165 mm height, 64-pin backplane connector on top, analog input terminal blocks on bottom, channel status LEDs on front
Functional Features:​ 8 independent AI channels with per-channel signal type configuration; software calibration with field-adjustable zero and span; wire-break detection; cold-junction compensation (for thermocouple input when paired with dedicated modules); onboard watchdog timer with automatic timeout reset.
Working Principle:​ Field 4–20 mA or 0–10 V signals enter via the bottom terminals, pass through signal conditioning circuitry (filtering and amplification), then are digitized by the 13-bit Σ-Δ ADC. Results are transferred over the backplane bus to the PLC/DCS CPU for PID computation or data display.
Application Scenarios:​ Process control, thermal power generation, petrochemical plants, gas turbine monitoring.
Installation Requirements:​ Plug-in backplane mounting. Ensure backplane supplies correct +5 V DC. Verify signal wiring matches configured input type per channel.
Usage Notes:​ Perform regular calibration checks. Confirm wire-break detection logic is mapped correctly in the control program. Maintain ambient temperature within specified range.
