Product Overview

Name: GE IS220PSCAH1A Power Supply & Control Accessory Module(XIONGBA) | XIONGBA
Price: 999.00 USD
Availability: InStock

The GE IS220PSCAH1A is a high-reliability power supply and control accessory module designed exclusively for GE’s Mark VIe control system—an industry-leading platform for critical industrial automation, particularly in power generation and heavy process industries. As a key power management component within the Mark VIe ecosystem, GE IS220PSCAH1A delivers stabilized, low-ripple power to connected I/O modules, processors, and communication interfaces, ensuring consistent performance of the entire control architecture. Its engineered design prioritizes compatibility with other Mark VIe components, making GE IS220PSCAH1A an essential building block for systems where uninterrupted power delivery directly impacts operational safety and efficiency.

Unlike generic power modules, GE IS220PSCAH1A is optimized for the harsh conditions of industrial environments, with robust circuitry that mitigates the effects of electrical noise, voltage fluctuations, and thermal stress. This specialization ensures that sensitive control components receive clean, reliable power, reducing the risk of data corruption, module downtime, or system-wide disruptions—critical for applications like turbine control, where even minor power inconsistencies can lead to costly shutdowns.

Main Features and Advantages

Ultra-Stable Power Delivery: GE IS220PSCAH1A achieves exceptional output voltage accuracy (±0.3%) and low ripple (<50 mV), ensuring sensitive Mark VIe components—such as RTD input modules or discrete output modules—receive consistent power. This stability eliminates voltage-related errors in data acquisition and control signals, a critical advantage for precision applications like turbine temperature monitoring and process regulation.

Robust Fault Protection: The module integrates multi-layer safeguards, including overvoltage (28 VDC cutoff), overcurrent (3.5 A trip), and overtemperature (75°C shutdown) protection. If an anomaly is detected, GE IS220PSCAH1A immediately isolates the fault to prevent damage to itself and connected equipment, minimizing repair costs and downtime in mission-critical systems.

Seamless Mark VIe Integration: Designed as a native Mark VIe component, GE IS220PSCAH1A communicates directly with the system backplane to share real-time status data (e.g., output voltage, load current, temperature). This enables operators to monitor power health via the Mark VIe HMI, simplifying troubleshooting and reducing the need for manual inspections of the module.

Industrial-Grade Durability: Constructed with high-temperature-rated components and a shielded enclosure, GE IS220PSCAH1A withstands extreme conditions common in power plants, oil refineries, and manufacturing facilities—including vibration (up to 5 g), electrical interference, and wide temperature swings. This ruggedness ensures long-term reliability, with a mean time between failures (MTBF) exceeding 100,000 hours.

Application Fields

GE IS220PSCAH1A is most critical in power generation facilities, where it serves as a primary power source for GE Mark VIe-controlled gas and steam turbine systems. In these applications, GE IS220PSCAH1A powers key components like the GE IS220PRTDH1B (RTD input module) and GE IS220PDOAH1B (discrete output module), ensuring these modules can accurately monitor turbine temperatures and control fuel valves or cooling systems. Without stable power from GE IS220PSCAH1A, turbine control systems may experience erratic behavior, leading to reduced efficiency or unplanned shutdowns.

Beyond power generation, GE IS220PSCAH1A is widely used in oil and gas processing plants, where it supports Mark VIe-based control systems for pipeline pressure regulation, pump control, and separator operations. Its ATEX Zone 2 certification makes it safe for installation in potentially explosive environments, while its noise immunity ensures reliable performance amid the electrical interference from compressors and motors.

The module also finds application in heavy manufacturing, such as steel and cement production, where it powers Mark VIe I/O modules that monitor and control kilns, conveyors, and heating systems. In these high-vibration, high-temperature settings, GE IS220PSCAH1A’s rugged design ensures continuous power delivery, preventing production delays caused by module failure.
