Product Overview
The GE IS220PPROS1B is a high-reliability redundant power supply module engineered for GE’s Mark VIe Speedtronic Turbine Control System, serving as a critical power backbone in industrial automation. Designed to deliver stable, uninterrupted power to control system components, this module ensures the reliable operation of gas turbines, steam turbines, and other mission-critical equipment in power generation, oil and gas, and heavy manufacturing.
Featuring dual independent power input channels and a hot-swappable design, the GE IS220PPROS1B provides regulated 24 VDC output (15 A max) with ±5% tolerance, safeguarding against single-point failures. Its internal monitoring circuitry continuously tracks input voltage, output current, and thermal status, triggering alerts via front-panel LEDs (Power A, Power B, Fault, OK) and remote diagnostics. The module’s compact 3U VME form factor (220 mm × 100 mm × 160 mm) and rugged construction—including a triple-layer conformal coating and IP20-rated enclosure—enable operation in harsh environments (-30°C to +65°C) with high vibration and humidity.
In automation systems, the GE IS220PPROS1B acts as the power hub for Mark VIe I/O modules (e.g., IS220PDIOH1B, IS220PAICH1A), ensuring consistent power delivery to sensors, actuators, and communication interfaces. Its ability to seamlessly switch between primary and secondary power sources (100–240 VAC or 24–125 VDC) minimizes downtime during input failures, making it indispensable for safety-critical applications like turbine emergency shutdown systems.

Main Features and Advantages
Redundant Power Delivery:
The GE IS220PPROS1B integrates dual input channels (AC or DC) with automatic failover, ensuring <10 ms switchover time between primary and secondary sources. This redundancy eliminates single points of failure, critical for maintaining operation in turbine control systems where even brief power interruptions can cause costly downtime.

Precise Voltage Regulation:
With ±5% output voltage tolerance and low ripple (<50 mV peak-to-peak), the module delivers stable 24 VDC to sensitive electronics like I/O modules and communication cards. This precision prevents voltage fluctuations that could corrupt data or damage components in Mark VIe architectures.

Rugged Industrial Design:
A triple-layer conformal coating protects against dust, moisture, and chemical exposure, while the module’s vibration resistance (10–2000 Hz, 10 G rms) and wide operating temperature range make it suitable for offshore platforms, refineries, and power plants.

Comprehensive Diagnostics:
Front-panel LEDs provide real-time status (Power A/B active, fault conditions), while internal sensors monitor temperature, input voltage, and output current. Fault data is logged and transmitted to the Mark VIe controller via IONET, enabling predictive maintenance to address issues like declining efficiency or component wear before failures occur.

Hot-Swappable Operation:
The GE IS220PPROS1B supports hot swapping, allowing replacement of a faulty unit without powering down the control system. This feature reduces mean time to repair (MTTR) to under 15 minutes, critical for maintaining uptime in mission-critical applications.

Installation and Maintenance
Pre-installation Preparation:
Before installing the GE IS220PPROS1B, verify the input voltage matches the module’s range (100–240 VAC or 24–125 VDC) and ensure the control cabinet is properly grounded to prevent electrostatic discharge (ESD). Use an ESD wrist strap during handling. Mount the module in a 3U VME rack with at least 50 mm clearance for airflow, securing it with anti-vibration brackets to minimize mechanical stress. Connect primary and secondary power sources to the terminal block, ensuring correct polarity, and link the output to the Mark VIe backplane for distribution to I/O modules.

Maintenance Recommendations:
Perform monthly visual inspections of front-panel LEDs to confirm both power channels are active (green) and no faults are present (red). Clean dust from ventilation slots using compressed air to maintain cooling efficiency. Quarterly, use a multimeter to verify output voltage (24 VDC ±5%) and check terminal connections for corrosion or looseness. Annually, update firmware via GE’s Proficy software to access efficiency improvements and compatibility updates. For redundant setups, test failover functionality by disconnecting one input source and confirming seamless switchover to the secondary channel.
