IS200EDCFG1A
GE
Overview
The IS200EDCFG1A is an Exciter DC Feedback Board from GE. It is part of GE's industrial automation product portfolio.
Application & Technical Notes
As an exciter dc feedback board, the IS200EDCFG1A is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.
Key published characteristics include an operating temperature range of -30 to 65 o C. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (-30 to 65 o C); do not exceed it during commissioning or in enclosed panels without airflow. Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the IS200EDCFG1A, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm mechanical and electrical compatibility with your GE product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

SPECIFICATIONS
Part Number: IS200EDCFG1A Manufacturer: General Electric Series: EX2100 Product Type: Exciter DC Feedback Board Operating Temperature: -30 to 65 o C Repair: 3-7 Days Country of Origin: USA Availability: In Stock Manual: GEI-100464A
FUNCTIONAL DESCRIPTION:
IS200EDCFG1A is an Exciter DC Feedback Board manufactured and designed by General Electric as part of the EX2100 Series used in Excitation Control Systems. At the SCR bridge, it detects field current and field voltage and communicates with the EISB board in the control panel through a quick fiber-optic link. High noise immunity and voltage isolation between the two boards are provided by fiber optics. Each signal travels on one of two fibers. The following are two fiber kinds that can be utilized for various distances:
Plastic-type fiber for distances up to 10 m Hard-clad silica type for distances up to 90 m

FIELD VOLTAGE FEEDBACK:
In accordance with the kind of bridge application, the field voltage feedback circuit offers seven choice settings to reduce the bridge voltage. The bridge's negative terminal and the current shunt's positive terminal are monitored to determine the field voltage. Signals are fed into a differential amplifier, which controls a voltage-controlled oscillator after the voltage has been scaled with the jumpered resistors.
FIELD CURRENT FEEDBACK:
At the SCR bridge, the field current is measured over a DC shunt. A low-level signal with a maximum value of 500 mV is produced as a result, and it is supplied into a differential amplifier. An oscillator with voltage control receives an output voltage from the amplifier that ranges from -5 V to +5 V.
POWER SUPPLY:
EDCF receives power from an outside source which is 24 V DC. Three voltage regulators generate +15 V dc, -15 V dc, and + 5 V dc from this. The output voltages of 15 V dc operate the PSOK green LED.
APPLICATION DATA:
The EDCF has a single green LED that shows the power supply is on (PSOK). The accompanying figure, Board Layout, depicts the layout of the EDCF board.

CONNECTORS:
The board receives 24 V dc through connection J16 and the voltage across the field current shunt resistance through connector P1. The connection for the field voltage input is stab-on (E1). Through fiber-optic links, the current and voltage feedback to the control.

This model is an exciter direct current feedback board, which measures field voltage and field current at the SCR bridge. To properly use this model it is necessary to connect it to the EISB board when done so two fiber-optic cables are used for one signal each. The two fiber-optic cables that can be used are plastic fiber, the plastic fiber cable is used for distances up to ten meters; and a hard-clad silica fiber cable, this cable is used for distances up to ninety meters. Please note that the minimum bending radius of these cables is each one and a half inches.
The field voltage feedback of the IS200EDCFG1A will always be measured across the negative terminal of the bridge device and across the positive terminal of the shunt. When the voltages have been scaled alongside the jumpered resisters the signals will proceed to be input to a different amplifier, this amplifier controls the VCO.
There are two manuals that can be used with the IS200EDCFG1A model, one of them is the general GEH-6632 EX2100 Excitation Control User’s Guide and the other is the GEI-100464 Exciter DC Feedback Board manual.
