Functional Features:

• Channel‑by‑channel electrical isolation to suppress field interference
• Each channel independent LED status indicator for on‑site fault diagnosis
• Support hot‑swap without system shutdown
• Built‑in input over‑voltage and surge‑suppression circuit
• Diagnose open‑circuit and over‑current fault of field loop
• Seamless configuration through Ovation DCS engineering software

Application Scenarios:

• Power‑plant boiler and turbine auxiliary equipment switch‑signal acquisition
• Petrochemical process on‑site limit‑switch, relay‑contact signal collection
• Water‑treatment plant interlock‑signal input for distributed control system
• Retrofit and spare‑part replacement of legacy Ovation DCS system

Performance Parameters:

• Input signal response time: ≤1 ms
• Isolation withstand voltage: 500 VAC 1 minute
• Channel input impedance: 3.3 kΩ
• MTBF: 285 000 hours

Material Composition:

• Circuit board: FR‑4 high‑Tg industrial PCB with conformal coating
• Optocoupler: High‑speed industrial‑grade opto‑isolation chip
• Housing: Flame‑retardant modified polycarbonate
• Terminal connector: Gold‑plated phosphor bronze contact terminal

Structural Characteristics:

• Standard Ovation card‑insert module form factor
• Front‑panel LED indicator array corresponding to each input channel
• Rear‑side back‑plane golden finger for bus communication
• Field‑signal access via matched terminal base unit

Working Principle: On‑site 24 VDC switch signal passes through surge‑suppression circuit and opto‑coupler isolation circuit. Convert field electrical level signal into internal digital logic signal, transmit data to DCS controller via back‑plane bus for logic operation processing.

Installation Requirements:

• Mount on matched Ovation I/O carrier base unit
• Field wiring must follow sinking/sourcing configuration requirement
• Keep cabinet ventilation, avoid high‑temperature stacking installation
• Complete channel‑by‑channel signal test after wiring completion
