  • Channel Count: 8 isolated analog inputs

  • Signal Types (Software‑Selectable):

    • Voltage: ±10 mV, ±50 mV, ±100 mV, ±5 V, ±10 V, ±15 V, ±20 V (extended ranges vs G01)

    • Current: 0–20 mA, 4–20 mA (passive, loop‑powered)

  • Resolution: 16‑bit (≤0.0015% of span)

  • Accuracy: ±0.05% of full scale (25°C); ±0.1% max across operating temp

  • Isolation: 1500 Vrms (channel‑to‑backplane, channel‑to‑channel)

  • Input Impedance:

    • Voltage: ≥1 MΩ

    • Current: 250 Ω (burden resistor)

  • Conversion Time: 10 ms per channel

  • Operating Temp: 0°C to 60°C

  • Storage Temp: -40°C to 85°C

  • Humidity: 5%–95% non‑condensing

  • Bus Interface: Ovation I/O bus (hot‑swap capable)

  • Connector: 50‑pin edge connector (mates with 1B30035H01 / 1B30053H01‑2 bases)

Key Features

  • Extended voltage ranges (±15 V, ±20 V) – covers higher‑voltage sensors/transmitters not supported by G01

  • 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
