5X00226G04: full factory ordering part number, G04 stands for hardware revision version; no interchange alternative part codes, fixed model for 16-channel HART AO module under Ovation platform.

Backplane power supply: 24VDC from Ovation rack backplane, module power consumption ≤7.2WChannel configuration: total 16 independent isolated AO channels, each channel standard 4~20mA analog output + HART digital superimposed signalSingle channel load resistance: max 750Ω for 4-20mA drive; HART communication impedance match compliant with IEC61158 standardOutput precision: full scale accuracy ±0.05%FS, 16-bit D/A conversion resolutionAmbient condition: operating -40℃~+70℃, storage -40℃~+85℃, 5%~95%RH non-condensing, vibration resistant conform IEC60068Dimension & Weight: standard single-slot Ovation card 152×82×215mm, net weight≈0.62kgIsolation design: channel-to-backplane galvanic isolation 1500VDC, inter-channel partial isolation for anti-interference

Rear golden finger: Ovation proprietary high-speed backplane bus, real-time data exchange with Ovation controllerFront side: docking port for Ovation dedicated AO terminal base to connect field HART equipment cableFront panel LED indicators: POWER, RUN, FAULT, 4 group channel status LED for power status, running state, module fault and channel abnormal alarmBuilt-in HART master chip, each channel supports independent HART polling, reading instrument tag, calibration data, equipment fault code remotely via DCS workstation

Convert digital control command from Ovation controller into standard 4~20mA current signal to drive field regulating valves and actuators to complete closed-loop process controlTwo-way HART communication: downward send remote calibration, parameter setting command to HART smart devices; upward upload instrument model, fault code, process auxiliary variable to DCS systemFull channel self-diagnosis: auto detect output open-circuit, short-circuit, over-load failure, alarm and record fault log on Ovation operator stationHot swap maintenance: replace module online without cabinet power off, unaffected operation of other intact channels, online download configuration via Ovation engineering software without system shutdown

Must install on specified Ovation single I/O slot and matching original dedicated terminal base; confirm slot coding before plug-in to avoid hardware damageField signal cable separate from high-voltage power cable during wiring to avoid EMI causing output drift and HART communication dropoutRegularly check front panel fault LED and DCS system fault log for over-load or short-circuit troubleshooting; tighten terminal wiring periodically to prevent poor contactWhen using HART multi-drop bus wiring, strictly control total loop load resistance to ensure stable digital communication of multiple field instruments on single channel
