Module Power Supply Input

The module draws operating power from the standard Ovation I/O rack backplane, fed by regulated 24 VDC chassis power. Under normal operating conditions, the typical power consumption is less than 8 W. It supports hot-swap functionality, enabling online module replacement without rack power interruption and ensuring continuous stable backplane power supply during maintenance operations.

Field Digital Signal Inputs

Equipped with 16 fully independent differential digital input channels, specially designed for high-precision Sequence-of-Event (SOE) signal acquisition and fault sequence recording. The module accepts two types of field signals: passive dry contact signals and active voltage discrete signals from on-site equipment. The nominal differential input voltage range is 24 VDC to 48 VDC.

Adopting high-impedance differential circuit design, the module delivers excellent electromagnetic interference resistance for complex industrial field environments. It supports high-accuracy timestamping to capture rapid signal state changes, meeting rigorous SOE recording requirements. Each channel is equipped with independent fuse protection to isolate single-channel faults and prevent fault spread across all input channels.

Internal Backplane Communication I/O

Features a bidirectional backplane data interface for system data interaction. It uploads real-time field contact status and high-precision timestamped event data to the Ovation main controller. Meanwhile, it receives remote configuration parameters, channel enable/disable settings and online diagnostic commands from the system controller. The module continuously uploads self-diagnostic status, including channel open-circuit faults and abnormal input signal alarms, to realize real-time system monitoring.

Status Indicator Output

Integrated front-panel LED indicators include power status LED, module running status LED and channel fault alarm LEDs. These visual indicators intuitively display power supply status, module operating health and abnormal conditions of each input channel, facilitating rapid on-site inspection and fault judgment.

Case 1: Boiler and Turbine Protection System of Thermal Power Plant

Project Profile

2×660 MW coal-fired thermal power units equipped with Emerson Ovation DCS system.

Application Deployment

Multiple 5X00357G02 modules are installed in boiler protection cabinets and turbine Emergency Trip System (ETS) cabinets. The module acquires critical protection discrete signals, including turbine trip relay contacts, boiler Master Fuel Trip (MFT) contacts, forced draft fan and induced draft fan fault feedback, boiler drum high and low water level switch signals, and pipeline pressure protection contact signals.

Implementation Effect

When the unit experiences load rejection or unplanned shutdown, the module records all protection actions and signal state changes with accurate timestamps. It enables maintenance personnel to clearly distinguish the initial fault trigger source and subsequent linkage actions, effectively avoiding misjudgment of protection maloperation and malfunction. The differential input architecture greatly resists strong electromagnetic interference from on-site high-voltage auxiliary equipment and prevents invalid or false event records. Meanwhile, the hot-swap function supports online module replacement during equipment standby maintenance without powering off the control rack, significantly improving system maintenance efficiency and operational availability.

Case 2: Combined Cycle Gas Turbine Power Plant

Project Profile

300 MW gas-steam combined cycle power generation unit.

Application Deployment

The 5X00357G02 module is applied to signal collection for gas turbine control systems, Heat Recovery Steam Generator (HRSG) protection systems, and generator excitation protection circuits. The monitored field signals mainly include flame detection contacts, unit purging sequence status, gas fuel shutoff valve position feedback, and generator overspeed protection dry contact signals.

Implementation Effect

Gas turbine startup, shutdown and load switching involve rigorous sequential interlock logic. The high-precision SOE function completely records the full process of equipment purging, ignition confirmation and fuel input switching. In case of gas turbine emergency tripping, operators can quickly locate the exact cause, such as flameout failure, fuel supply system abnormality or auxiliary equipment fault. Each channel adopts independent fuse protection design, which can isolate single-point channel faults and prevent local cable short circuits or signal anomalies from affecting the overall signal acquisition of the entire module.

Case 3: Governor and Excitation Control System of Hydropower Units

Project Profile

Large-scale river hydropower station with multiple hydroelectric generating units.

Application Deployment

The modules are deployed in unit integrated control cabinets to collect status signals of wicket gate servomotor limit switches, generator circuit breaker switching status, excitation system fault contacts and water level safety protection switches.

Implementation Effect

During unit load regulation, frequent startup and shutdown, and transient water hammer impact, the module continuously and stably captures state changes of mechanical and electrical protection signals. Complete SOE log data provides objective analysis basis for troubleshooting unit abnormal vibration, governor hunting and circuit breaker misoperation. Equipped with high-impedance differential input circuits, the module adapts to long-distance field wiring between the powerhouse and dam area, effectively suppressing ground loop interference and ensuring long-term stable signal acquisition.

Case 4: Cogeneration Plant for Chemical Industrial Park

Project Profile

Central heating and power supply cogeneration station supporting continuous operation of chemical industrial production lines.

Application Deployment

The 5X00357G02 module is configured for Burner Management System (BMS) and steam pipeline safety interlock systems. It collects key safety signals including burner flame failure contacts, steam overpressure safety valve action feedback, circulating pump fault alarm contacts and heat network isolation valve status signals.

Implementation Effect

The module achieves stable and continuous SOE recording, realizing full traceability of all safety interlock actions during thermal system load fluctuation and parameter deviation. Operation and maintenance engineers can optimize interlock logic thresholds and delay parameters based on event sequence data, effectively avoiding unnecessary full-system shutdowns caused by single auxiliary equipment faults, and improving the overall operational stability and continuity of the cogeneration system.

Case 5: Municipal Large-Scale Water Treatment Plant

Project Profile

Large-scale urban reclaimed water and sewage treatment plant based on Ovation DCS platform.

Application Deployment

The modules are responsible for collecting status signals of key process equipment, including water inlet gate switches, sludge dewatering machine operating contacts, aeration fan fault signals and chemical dosing system safety interlock contacts.

Implementation Effect

The module accurately records the chain shutdown sequence and state mutation events of biochemical treatment equipment. The sorted event data guides standardized equipment maintenance scheduling, realizes early identification of aging contactors and frequently tripped safety switches, reduces equipment hidden dangers, and effectively lowers the frequency of unplanned production and treatment process interruptions.
