I/O modules

Core Processing Capabilities

The GE IS200WREAH1APR3 executes real-time turbine control algorithms with precision. This module handles fuel management, inlet guide vane positioning, and exhaust temperature monitoring. It processes input signals from up to 24 analog and digital field devices. Consequently, the module maintains stable turbine operation across varying load conditions.

Physical Dimensions and Board Architecture

This control module measures 298 mm in total length. Its width reaches 210 mm for a full-size VME form factor. The board thickness stands at 24 mm including all component heights. You will find 534 discrete components on this multi-layer PCB. These include a 32-bit main processor, memory chips, and communication controllers. The GE IS200WREAH1APR3 weighs approximately 820 grams for robust mechanical stability.

Memory Configuration and Data Retention

The GE IS200WREAH1APR3 contains 16 MB of flash memory for firmware storage. It also includes 8 MB of SRAM for runtime data and control variables. A replaceable lithium battery preserves the SRAM contents during power outages. This battery provides a typical retention period of three years. The module does not use external memory cards or removable storage media.

Input and Output Interface Summary

This turbine control module provides 16 analog input channels with 16-bit resolution. It also offers 8 digital input channels for contact or proximity sensors. Furthermore, the module includes 8 digital output channels for actuator and relay control. Each output channel can sink up to 500 mA at 24 V DC. The board uses four 36-pin high-density connectors for all field wiring.

Energy Storage and Power Supply Details

The GE IS200WREAH1APR3 draws 750 mA from a 5 V DC logic supply. It also requires 200 mA from a separate 24 V DC field supply. The board incorporates eight 100 µF electrolytic capacitors for power rail decoupling. Total stored energy reaches approximately 0.32 joules at nominal voltage. The module dissipates 5.5 W of heat during normal operation. Therefore, the unit does not require forced-air cooling in most cabinets.

Component Count and Environmental Specifications

Installation and Compatibility Notes

You must install this module in a Mark VIe VME rack slot. The module synchronizes with a backup IS200WREAH1APR3 for redundant configurations. Always replace the lithium battery during scheduled maintenance every two years. Then, verify that all 36-pin connectors lock securely before powering the system. The unit operates reliably from -20°C to +65°C ambient temperature.
