Product Overview

The GE DS200EXPSG1A is an EXPS bulk power supply board used in GE industrial control equipment. Its documented functions include providing signals for AC and DC input-power measurement and limiting current when the supply is energized from a station battery. These functions make the board part of the power-supply assembly’s input-monitoring and protection circuitry, rather than a general-purpose I/O module.

Technical Specifications

Features

• Supports measurement of AC and DC input power
• Provides current-limiting action during station-battery energization
• Includes three protective fuses
• Has an on-board LED, reset button and test points
• Uses a JP1 jumper associated with the T1 transformer secondary  

Industries Served

Frequently Asked Questions

1. What is the main function of DS200EXPSG1A?
It is an EXPS bulk power supply board that supports input-power measurement and current limiting within the GE supply assembly.
2. Does the board handle both AC and DC input-power information?
Yes. The documented EXPS function provides signals for measuring both AC and DC input power.
3. What happens when the supply is energized from a station battery?
The EXPS board provides a current-limiting function for that operating condition.
4. What is JP1 used for?
JP1 is the board’s manually movable jumper associated with grounding the center tap of transformer T1’s secondary.
