Part Code Definition

5X00481G04: complete factory ordering PN for OCR1100 controller; suffix G04 stands for fixed hardware revision version, fixed configuration without cross-substitute part number under Ovation standard CPU series.

Technical Specifications

Backplane power: 24VDC supplied via rack backplane, typical power consumption ≤14W

Processing core: Intel architecture embedded CPU, maximum load capacity for whole station up to 32000 I/O process points

Control cycle: configurable scan period 10ms~30s, supports 5 independent parallel control tasks

SOE precision: event sequence resolution up to 1ms for DI fault & action record

Ambient working range: -40℃ ~ +70℃, storage -40℃~+85℃, humidity 5%~95%RH non-condensing, complies IEC60068 industrial anti-vibration standard

Dimension & Weight: standard Ovation single slot size 156×85×220mm, net weight approx 0.62kg

Redundancy mode: dual-controller hot standby, automatic bumpless failover within 50ms once master CPU fails

Interface & Communication Layout

Rear golden finger: proprietary Ovation backplane bus, high-speed data interaction with local rack DI/DO/AI/AO I/O cards

Front panel ports: dual Ethernet RJ45 for Ovation control network linking OWS/engineering workstation; dedicated debug serial port for offline program download and fault debugging

Front LED indicators: POWER, RUN, FAULT, REDUND, NET status lamps, separately display power supply, operating status, hardware fault, standby redundancy state and network link condition

Onboard storage: built-in flash memory for solidification of user control program and configuration parameters, no extra storage disk required.

Core Functions

Execute customized DCS control logic (PID regulation, interlock logic, sequence control) compiled by Ovation engineering software, compute output instruction to corresponding DO/AO field modules

Real-time gather all channel data from local and remote I/O racks, upload process value, equipment status and fault alarm to system operator station

Redundant backup operation: paired master-slave controllers synchronize program & real-time data all the time, automatic switch to standby unit without process interruption upon main controller breakdown

Built-in full self-diagnosis: real-time monitor CPU operation, network communication, backplane power and I/O bus status, abnormal alarm auto-recorded into DCS system history log.

Application Scenarios

Main control cabinet core controller of coal-fired power boiler, turbine, FGD & SCR denitrification unit; main DCS processor for petrochemical refining, chemical reactor and gas pipeline process control; water treatment & waste incineration plant Ovation system main control spare replacement.

Operation & Maintenance Notes

Install only into dedicated CPU slot of Ovation standard rack, confirm slot coding before plug-in to avoid backplane bus damage

Redundant configuration needs two identical PN controller cards paired, complete program synchronization via engineering tool after installation

Separate control network Ethernet cable from high-current AC power wire during wiring construction to prevent EMI communication interruption

Online hot swap allowed only after confirming standby CPU enters full synchronization status; regularly check front panel fault LED and system alarm log for early troubleshooting.
