Functional Features
- Software-configurable 4–20 mA and 0–20 mA input ranges
- Built-in open-wire detection
- Channel-level self-diagnostics with fault auto-disable
- LED indicators for channel status and faults
Application Scenarios
Process variable acquisition (temperature, pressure, flow, liquid level) in power plant process monitoring, petrochemical DCS, pharmaceutical production control, and metallurgical process control. Also serves as a LAN communication card in AC/DC2000 drive systems.
Installation & Usage Notes
- For analog input use: 4–20 mA signal wiring must use shielded twisted pair; ground shield at the control cabinet end only; maintain ≥ 200 mm separation from power cables.
- Input current must not exceed 25 mA.
- Channel range and signal type must be correctly configured in configuration software before wiring to prevent measurement deviation.
