• 16‑bit high resolution & ±0.05% accuracy for precise measurement

• Channel‑to‑channel isolation for high‑noise industrial environments

• Supports 4–20 mA loop‑powered transmitters (no external supply)

• Built‑in diagnostics: open‑circuit, over‑/under‑range detection

• LED status indicators (PWR, COM, FAULT) for quick troubleshooting

• Hot‑swap compatible (online replacement)

• Backward compatible with all Ovation DCS revisions

• Industrial‑grade surge/ESD protection

Application Fields

• Power generation (thermal, combined‑cycle, nuclear) – extended‑range analog monitoring

• Petrochemical, refining – high‑voltage sensor inputs (e.g., ±15 V pressure/level transmitters)

• Process plants requiring ±15 V/±20 V voltage measurement (e.g., motor control, valve positioning)

• High‑precision loops with wide‑span analog signals

• Ovation DCS I/O expansion for extended‑range AI needs
