IS200EROCH1ABB EX2100 GE Regulator Board

Product Overview

The GE IS200EROCH1ABB (IS200EROCH1ABB) serves as an exciter regulator options card.

It belongs to the EX2100 generator excitation control series.

The module provides key support for simplex and redundant regulator system backplanes.

Engineers mount this card into a single backplane slot to manage diagnostic interfaces.

Technical Specifications

Interface & Hardware Details

• Keypad connector provides 24 V DC redundant power to local bezel displays.
• RS-232C lines transfer keypad data at baud rates reaching 38.4 k.
• The tool port connects external laptops directly to the DSPX processor.
• An integrated DC converter isolates ground loops across the engineering tool port.
• The card routes +70 V DC power directly to the ECTB contact terminal board.

ISBus Routing & Diagnostic Capabilities

• Transceivers process ISBus signals between M1, M2, and C control racks.
• Direct uncoupled pathways speed up high-frequency signal exchange between DSP processor modules.
• A faceplate green LED verifies active board power status immediately.
• Onboard EEPROM stores hardware revision data, serial numbers, and board type ID.

Target Applications & Field Equipment

• Supports ground detector monitoring interfaces in utility power generator plants.
• Integrates keypad and servicing software connections in EX2100 excitation systems.
• Routes high-speed rack control signals in redundant exciter control panels.

Global PLC Spare HUB's Insight

During a hydro plant retrofit, noisy ground loops disrupted excitation laptop diagnostics.

Installing the GE IS200EROCH1ABB card resolved communication drops using its isolated DC converter.

Direct ISBus routing maintained clean signal integrity between M2 and C processor racks.

The +70 V DC output maintained stable contact wetting voltage across field tripping circuits.

Selection & Engineering Guidance

• Select IS200EROCH1ABB when retrofitting EX2100 excitation systems with local keypad options.
• Verify whether your setup requires ERBP simplex or ERRB redundant backplane mounting.
• Check that field contact relays match the +70 V DC wetting supply voltage.

Frequently Asked Questions

Q1: How does the tool connector protect connected laptop computers from ground potential differences?

A1: An internal DC converter provides complete ground loop isolation across the RS-232 tool port.

Q2: What power supply voltage does the faceplate keypad connector deliver to local displays?

A2: Pin 1 and Pin 7 deliver redundant +24 V DC power to connected keypad units.

Q3: Does the card support third-party ground detection devices in excitation panels?

A3: Yes, the module incorporates dedicated signal routing for both GE and third-party ground detectors.

Q4: Which serial communication protocols handle data exchange on the faceplate connectors?

A4: Keypad and tool ports utilize RS-232C, while ISBus channels utilize RS-485 and RS-422 standards.

Q5: How do operators verify active board power without software diagnostic tools?

A5: Observe the faceplate LED indicator, which illuminates green when power is applied.
