Description

Basic Information

  • Manufacturer: Emerson Automation Solutions

  • Series: Ovation DCS

  • Origin: United States

  • Function: High‑accuracy acquisition of 8 channels of analog voltage/current signals (mV, V, mA) from field sensors; converts to digital data for process monitoring and closed‑loop control.

  • Weight: Approx. 0.7 kg

  • Status: Original new / refurbished available

  • Warranty: 12 months

Specifications

  • Channel Count: 8 isolated analog inputs

  • Signal Types:

    • Voltage: ±10 mV, ±50 mV, ±100 mV, ±5 V, ±10 V

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

  • Resolution: 16‑bit (high resolution, ≤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 (fast scanning)

  • 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

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

  • Multi‑range software‑selectable inputs (mV/V/mA) for flexible sensor compatibility

  • Channel‑to‑channel isolation eliminates crosstalk in high‑noise environments

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

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

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

  • Hot‑swap compatible (replace online without system shutdown)

  • Backward compatible with all Ovation DCS revisions

  • Industrial‑grade surge and ESD protection for harsh industrial environments

Application Fields

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

  • Petrochemical, refining, and gas processing – flow, pressure, temperature, level

  • Pulp & paper, water/wastewater – transmitter signal acquisition

  • High‑precision process loops requiring 16‑bit resolution and 0.05% accuracy

  • Ovation DCS I/O cabinet expansion for analog input needs
