5X00226G01 is fixed factory order PN for Ovation HART AO module; suffix G01 denotes fixed hardware revision, corresponding alternative revision is 5X00226G04 without full interchange for hardware version difference.

Backplane power: 24VDC supplied via rack backplane, typical power consumption ≤7.2WChannel configuration: total 8 independent isolated AO channels, standard output range 4–20mA DC, support HART 5/7 protocol digital communication on each loopOutput precision: full-scale accuracy ≤±0.05%, load resistance max 750Ω per single channelIsolation parameter: channel-to-backplane optoelectronic isolation 1500VAC, inter-channel group isolation for anti-surge interferenceAmbient rating: operating -20℃~+60℃, storage -40℃~+85℃, 5%~95%RH non-condensing, conform IEC60068 industrial anti-vibration standardDimension & Weight: standard Ovation single slot 155×84×218mm, net weight≈0.40kgProtection design: per-channel short-circuit, overvoltage and reverse wiring protection.

Rear golden finger: Ovation proprietary backplane bus, high-speed receive control instruction from rack main processorFront docking port: lock connector matched exclusive AO terminal base for valve positioner, frequency converter field wiringFront panel LED: POWER, RUN, FAULT + grouped channel indicator lamps, display module power, operating status, hardware fault and each channel output stateOnboard HART circuit: independent HART modem for each channel, realize remote parameter reading/writing of HART smart instruments via DCS system.

Convert DCS internal digital control value into standard 4–20mA analog signal to drive field regulating valves, actuators and frequency converters for process closed-loop PID regulationBuilt-in full HART communication, upload smart device model, fault code, calibration data to Ovation operator station without extra handheld HART communicator on-siteFull online hot swap: replace module online without cabinet power cut, residual normal channels keep continuous output controlComplete self-diagnosis: detect output loop open circuit, short circuit and overloading automatically, fault information uploaded to DCS historical alarm log in real time.

Boiler fuel control valve, feedwater regulating valve analog output control for coal-fired power plant; turbine lubricating oil pressure regulating actuator drive; desulfurization absorption tower liquid level adjusting valve output; petrochemical reactor feed flow control cabinet spare replacement.

Only install into standard Ovation single I/O slot and matching original terminal base, confirm slot coding before plug-in to avoid backplane burnoutField 4–20mA HART signal cable separated from high-current AC power wire during wiring to avoid EMI causing output driftComplete HART instrument address configuration via Ovation engineering software after wiring and power-onPeriodically check front fault indicator and DCS alarm log for loop abnormal troubleshooting, fasten terminal screws regularly to eliminate poor contact.
