Key Features

• Differential input design provides superior noise immunity for high‑interference environments

• 1 ms high‑speed response and 1 ms SOE timestamp accuracy for precise event capture

• 32‑point density reduces cabinet space and wiring cost

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

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

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

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

• 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) – critical SOE & high‑speed interlocks

• Petrochemical, refining, and gas processing – high‑noise safety systems

• Monitoring of high‑speed limit switches, pressure switches, and relay contacts in EMI‑heavy areas

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

• Safety interlock and alarm systems requiring precise, noise‑immune event timing

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