  • Logic Thresholds:

    • ON: ≥18 VAC/VDC

    • OFF: ≤5 VAC/VDC

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

  • Input Impedance: ≥10 kΩ per channel

  • Response Time: ≤1 ms (high‑speed, typical)

  • SOE Resolution: 1 ms (per‑channel time stamping)

  • 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

  • High‑speed 1 ms response for fast‑changing field signals

  • SOE logging with 1 ms timestamp accuracy for event sequencing and troubleshooting

  • 32‑point density reduces cabinet space and wiring cost

  • Accepts 24/48 VAC/VDC field voltages (standard in power/process industries)

  • LED status indicators per channel (ON/OFF) for quick visual check

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

  • Advanced diagnostics: open‑circuit detection, voltage fault logging

  • Backward compatible with all Ovation DCS revisions

  • Industrial‑grade surge and ESD protection for harsh environments

Application Fields

  • Power generation (thermal, combined‑cycle, nuclear) – SOE & high‑speed interlocks

  • Petrochemical, refining, and gas processing – fast‑acting safety systems

  • Monitoring of high‑speed limit switches, pressure switches, and relay contacts

  • Motor control centers (MCC) and critical relay logic interfaces

  • Safety interlock and alarm systems requiring precise event timing

  • Ovation DCS I/O cabinet expansion for high‑speed digital monitoring
