1. Product Brief Introduction

2. Detailed Technical Specifications

2.1 Processing & Control Performance Specification

• Built-in high-performance industrial-grade processor, large-capacity onboard nonvolatile Flash & SRAM memory for storing control logic, configuration parameters and local historical data; configuration data will not lose after short-time power failure.

• Supports standard PID, cascade PID, feedforward control, logic interlock, SOE event sequence recording and custom advanced control algorithm operation; synchronous data scanning cycle configurable from 10ms~1000ms via Ovation engineering software to satisfy fast-response and slow-process control demands separately.

• Max expandable capacity: drives multiple I/O rack backplanes, matches full-series Ovation I/O modules including analog, digital and special HART/RTD cards for flexible cabinet I/O layout configuration.

2.2 Electrical Specification

• Rated input working power: standard industrial DC power supplied from cabinet power supply unit, internal multi-stage overvoltage, overcurrent, surge protection circuit to resist power grid instantaneous surge and abnormal voltage fluctuation on site.

• Internal bus isolation design between core processor circuit and external I/O bus circuit, isolation dielectric withstand voltage ≥1000V AC, suppress common-mode electromagnetic interference transmitted from field long-distance cables.

• Communication interface with built-in signal isolation chip, avoids ground loop interference caused by different earthing potential between cabinet and external equipment.

2.3 Environmental Working Specification

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

• Working relative humidity range: 5%~95% non-condensing; adaptable to conventional control cabinet dust and slight damp environment; forbidden installation in corrosive gas, oil mist and continuous liquid splashing areas.

• Full compliance with CE and EMC electromagnetic compatibility certification, satisfies global thermal power & petrochemical industrial environmental application standards.

2.4 Mechanical & Installation Specification

• Standard Ovation main rack plug-in structure, fixed by cabinet card slot buckle design, directly plugged into master control rack backplane via gold finger for bus and power docking, no extra wiring required for address setting (automatic slot address identification).

• Integrated active cooling fan for forced heat dissipation of internal high-power components; replaceable independent fan component for convenient field maintenance and spare part replacement.

• Flame-retardant metal+engineering plastic composite housing with shock-resistant structure to adapt cabinet vibration during long-term site running.

2.5 Diagnostic & Redundancy Specification

• Multiple onboard LED status indicators for power supply, running status, bus communication fault, redundant link anomaly and hardware failure, supporting quick on-site fault checking.

• Complete self-diagnosis function: automatically detect internal hardware fault, bus disconnection, communication timeout and memory abnormality; all fault codes, alarm logs and operation records uploaded to Ovation monitoring system in real time for remote fault alert and troubleshooting analysis.

• N+1 or 1:1 redundant backup available: standby module synchronizes all operation data with main module, seamless automatic switchover within milliseconds upon main module breakdown to ensure uninterrupted control of production process.
