The Emerson 1X00024H01 is an industrial-grade AC-DC regulated power supply module specifically designed for the Ovation Distributed Control System (DCS). Manufactured by Power-One for Emerson (formerly Westinghouse), its core function is to convert 100–240 VAC input into a stable 24 VDC output. It delivers continuous and reliable power to Ovation controllers, I/O modules, and field devices, and is suitable for harsh industrial environments such as power plants, petrochemical facilities, and water treatment plants. This module supports redundant configuration to ensure uninterrupted system operation, serving as a critical foundational component for the stable functioning of the Ovation DCS.
Core Technical Specifications
Input Specifications
The input voltage ranges from 100–240 VAC at a frequency of 50/60 Hz, compatible with most industrial power supply standards worldwide. The input current is approximately 8–12 A (varies with input voltage), featuring wide voltage adaptability to cope with grid fluctuations.
Output Specifications
The standard output is 24 VDC, configured with two independent output channels rated at 12 A and 8 A respectively, delivering a total output power of 500 W to meet the simultaneous power supply needs of multiple modules. It boasts high output precision along with low ripple and noise characteristics, ensuring stable transmission of control signals.
Physical and Environmental Parameters
It adopts a DIN rail mounting design for easy integration into Ovation system cabinets. The operating temperature range is -10°C to +50°C, with a storage temperature range of -20°C to +70°C. The module has obtained international safety certifications including CE, UL, and CSA, and its protection performance meets industrial-grade requirements.
Electrical Protection
Built-in protection circuits against overvoltage, overcurrent, short circuit, and overtemperature are integrated. In the event of faults such as abnormal loads or out-of-limit environmental conditions, the module can automatically cut off or current-limit the output, preventing damage to itself and downstream equipment. It supports redundant power supply architecture, and in combination with dual-diode isolated output, achieves seamless switching to enhance system availability.
Core Features
Redundancy-Compatible Design
It is compatible with the redundant power supply configuration of the Ovation system and can operate in parallel with modules of the same model. A single module failure will not affect the overall power supply, ensuring the continuous operation of critical control processes. The two independent output channels can supply power separately, reducing the risk of single-point failures.
High-Efficiency and Stable Operation
Equipped with advanced power conversion circuits, it achieves a power factor of over 0.92 and high conversion efficiency, minimizing energy consumption and heat generation. The fanless design (for some versions) reduces the probability of mechanical failures and improves long-term operational reliability, making it suitable for harsh industrial environments with dust and vibration.
Easy Integration and Maintenance
With a compact size, it can be directly mounted on standard DIN rails without additional cabinet modifications. The wiring terminals are clearly labeled and support hot-swapping; module replacement requires no complex debugging, thus shortening system downtime. Some versions support communication protocols such as Modbus, enabling remote monitoring of output voltage, current, and module status to facilitate predictive maintenance.
