Description​

The GE IC698PSA100E​ is a robust 100-watt industrial power supply module manufactured by General Electric (now part of Emerson Automation) for the PACSystems RX7i platform . It serves as the core power unit for RX7i control systems, converting AC or DC input into stable 24V DC power to support CPUs, I/O modules, and communication cards . Designed for critical applications, it features hot-swap capability, redundant configurations, and compliance with IEC 61010 safety standards, ensuring reliability in demanding environments like power generation and chemical processing .

Application Scenarios​

In a chemical plant’s polymerization reactor control system, a sudden power supply failure could trigger an emergency shutdown, risking material loss and safety hazards. Here, the GE IC698PSA100E​ demonstrates its value through a redundant setup: two modules operate in parallel, with one seamlessly taking over if the other fails. This design prevented a reactor shutdown during a grid fluctuation at a large LNG facility, avoiding $2M in potential losses . Such scenarios underscore the module’s role in ensuring zero-interruption power for continuous processes .

Technical Principles and Innovative Values​

Active Current Sharing and Redundancy: The IC698PSA100E​ uses parallel architecture with active current balancing, allowing dual modules to share loads equally. If one fails, the other assumes full power within milliseconds (<5ms switching time), eliminating downtime .

Fanless Thermal Management: Its natural convection cooling eliminates fans, reducing failure points and maintenance needs while operating at up to 60°C ambient temperature .

Wide Input Voltage Range: Accepts 85–264V AC or 100–300V DC, enabling global deployment without external converters .

Integrated Diagnostics: LED indicators and Proficy Machine Edition software integration provide real-time health monitoring, enabling predictive maintenance .

Application Cases and Industry Value​

A natural gas liquefaction (LNG) plant integrated redundant GE IC698PSA100E​ modules into its compressor anti-surge control system. Over three years, the setup endured multiple grid disruptions without shutdowns, safeguarding against $2M-per-incident losses. The plant manager noted: “The redundancy of the IC698PSA100E​ ensured continuous operation during power dips, directly protecting revenue and safety”. This highlights the module’s value in critical infrastructure where reliability translates to risk mitigation .
