Description
GE DS3800HXRC1B1A
Technical Specifications
- Part Number: DS3800HXRC1B1A
- Series: Mark IV / Speedtronic
- Function: Relay Control / Discrete Output
- Voltage Rating: Compatible with standard industrial control voltages
Functional Features
- Discrete Output Control: Drives external relays, solenoids, and indicator lights.
- Optical Isolation: Protects internal logic from high-voltage field transients.
- Status Feedback: Provides visual LED indication of output states.
Application Scenarios
Gas and steam turbine control systems, emergency trip systems, and auxiliary equipment control panels.
Performance Parameters
- Switching Speed: Fast relay actuation for critical safety functions.
- Contact Rating: Rated for continuous industrial load currents.
Material Composition
Industrial-grade PCB populated with high-reliability relays, optical isolators, and driver transistors.
Structural Characteristics
Standard Eurocard form factor with backplane edge connectors and front-panel diagnostic LEDs.
Working Principle
Logic signals from the main processor are routed through optical isolators to energize relay coils, which in turn close or open contacts to control external field devices.
Installation Requirements
- Insert into an available slot in the Mark IV chassis.
- Verify backplane wiring matches the control schematic.
- Secure the board with retaining hardware.
Usage Precautions
- Never exceed the specified voltage or current ratings of the relay contacts.
- Replace only with identical or manufacturer-approved equivalent part numbers.
- Observe strict ESD safety measures.
