Description
Emerson 1X00797H01L Product Description
1. Product Overview
Emerson 1X00797H01L is a high power DIN rail mounted 24VDC power supply module of Ovation DCS 1X series, originally designed by Westinghouse. It provides stable and continuous power supply for Ovation controllers, I/O units, communication cards and field industrial instruments. Equipped with wide voltage input, high efficiency power conversion and full protection circuit, this module supports redundant parallel operation and hot swap maintenance. It maintains stable working performance under complex industrial conditions, and serves as the core power distribution unit widely used in power, chemical, oil gas and metallurgy industries.
2. Core Functions
2.1 Wide Voltage Input and Steady Output
The module accepts universal AC input ranging from 85VAC to 264VAC with frequency 47Hz to 63Hz, adapting to different power grid standards worldwide. It outputs constant 24VDC power with rated continuous current 20A and rated power 480W. Low ripple and noise design effectively avoid signal interference, and voltage fluctuation stays within small range under variable load conditions to guarantee consistent power supply quality.
2.2 High Efficiency Heat Dissipation Structure
Adopting high performance power conversion circuit, the maximum conversion efficiency reaches 90%. Natural convection fanless cooling structure eliminates failure risks caused by fan aging and dust accumulation. Industrial grade circuit coating enhances internal insulation, enabling long time stable operation in dusty, humid and salt mist environments.
2.3 Multiple Safety Protection Mechanism
Built with complete protection functions including overload protection, short circuit protection, overvoltage protection, overtemperature protection and reverse polarity protection. The module limits current automatically when overload occurs and recovers after fault removal. It cuts off output instantly to prevent component damage once short circuit, overvoltage or overheating happens. Reverse connection lock function effectively avoids burnout caused by wrong wiring.
2.4 Redundant Backup and Hot Swap Maintenance
Supports dual module redundant parallel connection with automatic load sharing. When one power module breaks down, the other module takes over all power supply work within 10ms without power interruption and data loss. Standard DIN rail installation allows online hot swap replacement. Maintenance work can be finished without shutting down the whole DCS system, effectively reducing production downtime.
2.5 Strong Environmental Adaptability
Operating temperature ranges from 0 degree Celsius to 55 degree Celsius, storage temperature covers minus 40 degree Celsius to 85 degree Celsius. The mechanical structure meets international vibration and shock resistance standards, resisting impact and vibration generated by on-site mechanical equipment. It keeps reliable operation under extreme temperature change and harsh working surroundings.
2.6 Status Diagnosis and System Compatibility
Front panel LED indicators directly display power supply, running and fault status for quick on-site inspection. Remote monitoring function supports real time viewing of output voltage, operating current, internal temperature and fault records. The module is fully compatible with Ovation DCS system version 3.7 and above, matching OCR series controllers and all 1X series I/O modules, easy for system expansion and spare parts replacement.

6. Installation and Maintenance
Install the module on vacant standard DIN rail inside cabinet, reserve enough ventilation space and keep distance from high power interference equipment. Fasten the module firmly and leave proper gap between adjacent modules for heat dissipation. Select matched copper wire for wiring, strictly distinguish positive and negative polarity. Separate power cable and signal cable to reduce electromagnetic interference. Equip overload protection switch on input and output terminal.
Check indicator light and module appearance every week, inspect wiring tightness and surface dust accumulation regularly. Clean dust with dry soft cloth, avoid corrosive cleaning liquid. Observe remote operation data daily to master real time operating condition.
Cut off external load power when fault occurs. Check input power supply, wiring circuit and load working state. Confirm overload and short circuit problems first. Restart the module after troubleshooting. Replace spare module timely if internal hardware failure appears.
