Fanuc Corporation| GE Fanuc Exciter Selector Board - IS200ESELH1A
The IS200ESELH1A Exciter Selector Board, originally part of General Electric's EX2100 series, is designed to interface with EMIO systems by receiving six logic level pulse signals. These signals are transmitted through a set of six cables to EGPA boards for distribution. When redundancy is required, two IS200ESELH1A boards must be employed simultaneously.Â
The IS200ESELH1A Exciter Selector Board, originally manufactured by General Electric under the EX2100 series, plays a crucial role in the operation of excitation systems. Designed to interface with the EMIO (Exciter Main Input/Output), this board receives six logic level pulse signals from the connected EMIO unit. These signals are transmitted through a set of six cables and distributed to EGPA (Exciter Gate Pulse Amplifier) boards within the system.Â
In scenarios requiring redundant controls, two IS200ESELH1A models must be employed simultaneously to ensure continuous operation and reliability. As an ESEL1 model, this board configuration necessitates only one bridge driver, reflecting its specific role within the broader EX2100 system architecture.Â
The functionality of the ESEL model is integral to the overall operation of the EX2100 system. It primarily facilitates the transmission of gate pulse signals to the EGPA boards. Upon reception by the EGPA boards, these signals are utilized to control SCR (Silicon Controlled Rectifier) gate firing processes, critical for maintaining stable and precise excitation control in turbine and generator systems.Â

Maintenance Tips
-
Visual Inspection: Regularly inspect the board for signs of visible damage such as burnt components, damaged connectors, or cracked traces, particularly in high-power areas.
-
Clean the Board: Use dry compressed air or an anti-static brush to remove any dust, dirt, or debris. Avoid liquid cleaners that could cause short circuits or damage to sensitive components.
-
Inspect Solder Joints: Check for cold or cracked solder joints, especially around high-power components. Damaged joints can lead to unstable performance or failure of the selector board.
-
Verify Input and Output Signals: Ensure the input and output signals are within their specified voltage ranges. Improper signal levels can cause incorrect operation or failure of the exciter system.
-
Monitor Voltage Levels: Regularly check the voltage levels to ensure the board is operating within its rated input specifications. Voltage spikes or fluctuations can damage the board or cause erratic performance.
-
Run Diagnostics: Use diagnostic software or tools to test the board’s functionality. Monitor for error codes or abnormal behavior that could indicate potential issues with the exciter system.
-
Temperature Monitoring: Ensure that the board is operating within its recommended temperature range. Overheating can degrade component life and reliability, leading to possible system failure.
-
Inspect Connectors and Wiring: Check connectors and wiring for secure attachment, wear, or corrosion. Faulty connections can cause intermittent signals or system instability.
-
ESD Protection: Always use electrostatic discharge (ESD) protection, including wrist straps and anti-static mats, when handling the board to prevent damage to sensitive components.
-
Ensure Proper Mounting: Verify that the board is securely mounted within the system, avoiding mechanical stress that can lead to disconnections or board damage during operation.
