1. Product Brief Introduction

2. Detailed Technical Specifications

2.1 Processing & Control Performance

• Equipped with high-performance industrial dedicated processor, onboard large-capacity Flash nonvolatile storage + SRAM cache for storing user control configuration, PID parameters, interlock logic and local operation logs; configuration data remains intact during short-time cabinet power failure.

• Configurable control scan cycle: 10ms~1000ms via Ovation engineering software; supports standard PID, cascade/feedforward PID, logic interlock, timing control, SOE event capture and user-defined advanced control algorithms.

• Single module can drive multiple I/O sub-racks, compatible with full-range Ovation AI/AO/DI/DO/RTD/HART special I/O modules for flexible cabinet layout expansion.

2.2 Electrical Parameters

• Rated working power: DC power supplied from cabinet internal power distribution unit; built-in multi-stage overvoltage, overcurrent and surge suppression circuit to resist grid instantaneous voltage surge and field power fluctuation.

• Isolation specification: ≥1000V AC isolation withstand voltage between core control circuit and backplane I/O bus, independent opto-isolation for external communication ports to eliminate ground loop interference caused by different earthing potential of field equipment.

• Low ripple internal power conversion design, effectively restraining common-mode and differential-mode electromagnetic interference coupled from long-distance field signal cables.

2.3 Environmental Specification

• Continuous operating ambient temperature inside control cabinet: 0℃ ~ +60℃; storage & transportation temperature: -40℃ ~ +85℃.

• Operating relative humidity: 5%~95% RH non-condensing; applicable for standard cabinet slightly dusty and damp environment; forbidden installation in surroundings with corrosive gas, continuous liquid splashing and dense oil mist.

• Complies with CE certification and industrial EMC electromagnetic compatibility standards for power & chemical industry site application.

2.4 Mechanical & Installation Specification

• Standard Ovation rack plug-in card structure, directly inserted into main control rack backplane via gold finger for bus communication and power supply docking; slot address auto-recognition without manual parameter setting.

• Built-in passive heat dissipation structure + auxiliary cooling duct layout; multiple LED indicator lights (Power/Running/Bus Fault/Redundancy Link/Hardware Alarm) on front panel for on-site rapid fault diagnosis and status checking.

• Flame-retardant alloy composite housing with anti-vibration structural design, adapting to long-term cabinet running vibration of power plant and chemical plant site.

2.5 Diagnosis & Compatibility Features

• Full self-diagnosis function: automatically detect internal hardware failure, bus disconnection, communication overtime, memory abnormality; all fault codes and alarm logs uploaded to Ovation monitoring system in real time for remote troubleshooting.

• Full backward compatibility with Ovation mainstream DCS hardware versions, can replace legacy CCM models for cabinet spare part upgrading and equipment renovation; matches complete Ovation engineering configuration software.
