Part Code Definition

1C31xxx = Ovation compact remote I/O personality module serial prefix

224 = exclusive model code for 8-channel universal AI card

G01 = first generation hardware revision version

Technical Specifications

Power supplied by rack backplane 5VDC bus, typical power consumption 4.8W;

8 independent isolated input channels, configurable signal:4~20mA DC / 0~5VDC / 0~10VDC, default factory setting 4-20mA current input;

A/D conversion resolution:14bit, full-scale measuring precision ≤±0.15% at 25℃;

Group isolation: every 4 channels form one isolation group, channel-group & group-backplane isolation voltage 1500VAC dielectric withstand;

Built-in per-channel overvoltage, reverse connection and surge protection up to ±6kV EMC level;

Working ambient: -40℃~+70℃, 5%~90%RH non-condensing; supports hot plug on Ovation standard I/O rack; net weight approx 0.45kg, dimension:122×53×168mm.

Interface & Communication Layout

Rear golden finger connects chassis backplane for Ovation internal bus data transmission;

Front side terminal wiring port for field transmitter shielded cable access;

Front panel LED indicators: RUN running lamp, module fault lamp, per-channel input abnormal alarm indicator.

Core Functions

Multi-type analog signal acquisition and high-precision AD conversion;

Real-time data upload to Ovation main controller for pressure, temperature, flow, liquid level monitoring;

Per-channel independent fault diagnosis: open circuit, short circuit, signal over-range, fault information auto uploaded to DCS for alarm log;

Online channel signal range parameter configuration via Ovation system software without offline module;

Single-channel abnormal state does not affect normal operation of remaining 7 channels.

Application Scenarios

Thermal power plant boiler drum level, main steam temperature, feedwater flow transmitter signal collection; petrochemical refining pipeline pressure, tank level analog signal input for DCS monitoring cabinet replacement and I/O expansion.

Operation & Maintenance Notes

Field instrument wiring adopts shielded twisted pair, single-end shielding grounded inside control cabinet;

Separate analog signal cable from high-current AC power wire to avoid electromagnetic interference;

Periodically check terminal wiring tightness and channel real-time input value; replace module when persistent channel acquisition failure after field circuit troubleshooting.
