Description
GE DS3800HIOD1G1G Digital I/O Board
Product Overview
The GE DS3800HIOD1G1G is a high-performance Digital Input/Output (I/O) Board designed for GE’s Mark IV Speedtronic turbine control system, serving as a critical interface for binary signal communication in industrial gas and steam turbine applications. As part of the DS3800HIOD series, this module integrates seamlessly with Mark IV microprocessor controllers, HMIs, and network devices to enable real-time data exchange, signal conditioning, and control logic execution in mission-critical environments .
Engineered with dual modular connectors and field-configurable jumpers, the GE DS3800HIOD1G1G supports industrial-standard digital signals (5V, 12V, or 24V DC), ensuring compatibility with legacy sensors, actuators, and modern automation systems. Its dual-sided PCB houses integrated circuits like AM26LS30 dual differential drivers and AM26LS33 quad differential receivers, which facilitate noise-resistant signal transmission across long cable distances. The module features three LED indicators (two red, one green) for real-time status monitoring of power, data transmission, and fault conditions, enhancing diagnostic visibility during operation .
While the Mark IV series is legacy technology, the GE DS3800HIOD1G1G remains indispensable for maintaining industrial infrastructure in power plants, offshore platforms, and heavy manufacturing facilities. Its six field-configurable jumpers allow users to adjust voltage thresholds, signal conditioning parameters, and communication protocols without hardware modifications, making it adaptable to diverse control scenarios .
