1. Basic Information

• Part Number: 5X00109G02

• Manufacturer: Emerson (Westinghouse)

• Module Type: HART-enabled high-performance isolated analog input (AI) module

• Compatible System: Ovation DCS Distributed Control System

• Mounting Mode: Standard Ovation I/O backplane rack plug-in installation

• Maintenance Feature: Hot swappable, module replacement without system shutdown

• Net Weight: Approximately 0.5 kg

2. Technical Specifications

2.1 Signal Input Parameters

• Input signal: Standard 4–20mA DC current signal, supports superimposed HART digital signal multiplex transmission

• Isolation design: Each channel is independently galvanically isolated from the system backplane; single-channel short circuit, overload or wiring fault will not interfere with other normal working channels

• A/D conversion: 16-bit high resolution, high measurement stability

• Full-scale measurement accuracy: ≤±0.1% FS

• Input impedance: Matched 250Ω sampling resistor for 4–20mA current loop

• HART function: Complies with standard HART protocol, realizes remote parameter modification, fault diagnosis and status feedback of on-site intelligent transmitters, compatible with asset management system (AMS)

• Each channel integrates open-circuit detection, overload, short-circuit and overvoltage protection circuits to avoid module burnout caused by field wiring errors

2. Electrical Parameters

• Power supply: Powered by DCS backplane 24VDC, no external auxiliary power supply required

• Total power consumption: Less than 5W, will not bring extra load burden to the control system backplane bus

2. Environmental & Certification Indicators

• Operating temperature range: 0℃ ~ +60℃

• Storage temperature range: -40℃ ~ +85℃

• Relative humidity: 5%–95% RH, non-condensing

• Fully complies with IEC international EMC electromagnetic compatibility standards, shock-resistant, vibration-resistant and dust-proof

• Has obtained CE, UL, CSA international industrial safety certifications

2. Diagnosis & Maintenance Functions

• Real-time automatic self-inspection continuously monitors channel open circuit, signal over-range, loop disconnection and power supply abnormalities

• Fault codes and abnormal details are uploaded to the upper DCS controller via backplane bus in real time for rapid fault location and troubleshooting

• Plug-and-play hot-swap structure greatly shortens on-site maintenance downtime and improves the overall continuous operation rate of the automation system

• Supports user-defined channel safety fallback values to stabilize control logic output when field signals are lost
