Product Overview: GE IS200ERBPG1ACA

The IS200ERBPG1ACA acts as the central backbone for EX2100 excitation systems. Specifically, it connects all boards within the regulator control system. The ERBP functional abbreviation stands for Exciter Regulator Backplane. This IS200ERBPG1ACA device was manufactured in General Electric’s Salem, Virginia facility. Furthermore, it is part of the Mark VI turbine control series.

Technical Specifications

The IS200ERBPG1ACA has a revision level of ACA. This indicates a three-fold extended revision table for the base ERBP design. The functional abbreviation ERBP provides a shortened alternative to the full part number. This board is a normal assembly type made in the USA.

The IS200ERBPG1ACA includes 12 analog input channels. The input span is 4-20 mA for standard process signals. Common mode voltage range is ±5 V for flexible wiring. Maximum lead resistance is 15 Ω per channel. Analog output current ranges from 0-20 mA.

Physical Characteristics

The IS200ERBPG1ACA has a distinctive rectangular enclosure. One side remains open for inserting various components and cards. Several areas on the board are perforated for airflow. The edges include flanges with small mounting holes. A small airflow fan is installed toward the rear surface.

The IS200ERBPG1ACA includes a board identification serial bus. Every installed board has a programmed ID device. This ID stores the barcode serial number and board type. It also records the hardware revision for traceability.

Backplane Architecture

The IS200ERBPG1ACA uses a non-VME compliant architecture. However, it provides 3U and 6U VME-style connectors. Specifically, it offers 96-pin or 128-pin DIN backplane connectors. Power distributes to mounted boards through these connectors. The IS200ERBPG1ACA includes master selection jumpers for redundancy.

Backplane Features of the IS200ERBPG1ACA:

• Architecture: Non-VME compliant

• Connector Types: 96-pin and 128-pin DIN

• Power Distribution: Via backplane connectors

• Slot Count: 13 or 21-slot VME rack compatible

• Redundancy: Master selection jumpers provided

• Board ID Bus: Serial communication for all slots

The IS200ERBPG1ACA provides communication among several board types. These include IGBT driver boards and EPSM power supplies. ERDD and ERIO boards also connect through this backplane. Additionally, ACLA and DSPX boards mount within the ERBP. For a full list, refer to GE manual GEI-100488a.

Compatible Boards

The IS200ERBPG1ACA works with a specific set of circuit boards. Each board plugs into the backplane connectors. The ERBP then routes power and signals between them. The backplane supports both simplex and redundant configurations.

Boards Compatible with the IS200ERBPG1ACA:

• IGBT: Gate driver boards for power modules

• EPSM: Exciter power supply modules

• ERDD: Exciter relay and digital output boards

• ERIO: Exciter remote I/O boards

• ACLA: Analog control and logic boards

• DSPX: Digital signal processor boards

The IS200ERBPG1ACA connects some boards via cable connectors. Others mount directly into the backplane slots. The board ID device interfaces with the slot-specific control. This provides automatic configuration and diagnostics.

Electrical Specifications

The IS200ERBPG1ACA operates on power distributed from the rack. It provides regulated power to all mounted boards. The backplane includes protection circuits for overvoltage events. Overcurrent protection is also built into the design. These features safeguard the entire excitation system.

• Input Channels: 12 analog (4-20 mA)

• Common Mode Voltage: ±5 V range

• Lead Resistance Max: 15 Ω

• Analog Output: 0-20 mA current loop

• Operating Temp: -30°C to 65°C

• Manual Reference: GEI-100521A

The IS200ERBPG1ACA supports both simplex and redundant regulator applications. Master selection jumpers determine the operating mode. For redundant systems, two backplanes work in parallel. Consequently, failure of one does not stop excitation control.

Control System Integration

The IS200ERBPG1ACA integrates with the Mark VI turbine control system. It also works as part of the EX2100 digital excitation scheme. This is GE’s third-generation excitation control system. The IS200ERBPG1ACA assimilates with the Mark VI HMI seamlessly. Therefore, no additional interface hardware is required.

Integration Options for the IS200ERBPG1ACA:

• Mark VI HMI: Full compatibility via CIMPLICITY

• Standalone Retrofit: Using Ethernet Modbus or serial

• Communication: RS-485, Ethernet, Modbus protocols

• SCADA Integration: Via communication ports

• Redundancy: Hot standby exciter regulators

The IS200ERBPG1ACA can function in standalone retrofit applications. It communicates using Ethernet Modbus or serial protocols. This allows integration with non-GE control systems. Consequently, the board extends the life of older turbine installations.

Environmental Specifications

The IS200ERBPG1ACA operates in typical industrial control rooms. The temperature range is -30°C to 65°C. This suits most turbine control environments. Airflow is enhanced by the integrated rear fan. Therefore, no external cooling is typically required.

• Operating Temperature: -30°C to 65°C (-22°F to 149°F)

• Storage Temperature: -40°C to 85°C typical

• Humidity: 5% to 95% non-condensing

• Cooling: Integrated fan on rear surface

• Vibration: Standard for rack-mounted equipment

• Altitude: 0 to 2000 meters without derating

The IS200ERBPG1ACA has perforated areas for airflow. These openings allow heat to escape from power components. Keep these perforations clear of dust and debris. Blocked airflow can cause overheating and premature failure.

Mark VI Series Context

The IS200ERBPG1ACA belongs to the Mark VI Speedtronic system. Mark VI was developed throughout the 1990s for turbine regulation. It improved upon the earlier Mark V industry standard. Specifically, Mark VI added wind turbine applications to existing gas and steam options. The IS200ERBPG1ACA serves all three turbine types.

Turbine Applications for the IS200ERBPG1ACA:

• Gas Turbines: Excitation and speed control

• Steam Turbines: Field regulation and protection

• Wind Turbines: Generator excitation management

• Hydro Turbines: With appropriate excitation systems

• Compressor Drives: Large synchronous motors

The IS200ERBPG1ACA is not GE’s original ERBP design. The IS200ERBPG1 parent board came first. This ACA revision adds three levels of updates. Consequently, it includes improvements in reliability and features.

Termination Connections

The IS200ERBPG1ACA connects to termination boards externally. These use box-type or barrier terminal blocks. Field wiring terminates on these separate boards. This isolation protects the backplane from field wiring faults. It also simplifies replacement without rewiring.

• Termination Type: Box-type or barrier blocks

• Connection Method: Ribbon cables or discrete wiring

• Field Wiring: 0.2 to 2.5 mm² (24 to 14 AWG)

• Isolation: Provided by termination boards

• Shielding: Recommended for analog signals

Power connectors are provided on the front of the IS200ERBPG1ACA. These supply power to external boards it supports. Fan power output is also available from these connectors. Always verify voltage ratings before connecting external loads.

Installation Guidelines

Mount the IS200ERBPG1ACA in a 13 or 21-slot VME card rack. Specifically, insert it into the designated exciter regulator slot. Secure the board with the front panel screws. Connect the termination boards using appropriate cables. Finally, apply power and verify status LEDs.

Key Installation Points for the IS200ERBPG1ACA:

• Rack Type: 13 or 21-slot VME card rack

• Slot Position: As specified in EX2100 manual

• Grounding: Ensure rack is properly grounded

• Fan Check: Verify rear fan operates after power-up

• Board ID: Confirm ID bus communication active

For redundant applications, install two IS200ERBPG1ACA backplanes. Configure the master selection jumpers appropriately. One board acts as primary while the other stands by. The switchover is automatic upon primary failure.
