Beskrivelse
Product Overview
The GE IS200ESELH3A is an Exciter Selector (ESEL) board manufactured by General Electric as part of the EX2100 Excitation Control System. Mounted directly in the control rack, this module receives six logic-level gate pulse signals from the Exciter Master I/O (EMIO) board and routes them through six dedicated cable sets to the Exciter Gate Pulse Amplifier (EGPA) boards in the Power Conversion Cabinet. With a physical size of 33.02 cm x 10.16 cm (13.0 in x 4.0 in) and an estimated net weight of 1.20 kg (2.65 lbs) [shipping weight: 2.72 kg / 6 lbs], it plays a critical role in accurately timing SCR firing for stable generator output regulation.
Key Advantages
- Six-Bridge Driver Architecture: Equipped with six bridge drivers specifically designed for Group 3 variations, providing precise drive signals for SCR firing controls.
- Streamlined & Low-Maintenance Design: Engineered without jumpers or test points, eliminating potential configuration errors and simplifying overall system diagnostics.
- Real-Time LED Diagnostics: Features three front-panel green status LEDs (Power Supply, Active/Enabled state from Control C, and Gate Input Activity from EMIO) for immediate visual monitoring.
- Seamless VME Backplane Integration: Communicates with the system via P1 and P2 VME backplane connectors for reliable signal routing to EGPA amplifiers in redundant or simplex control setups.
- Compact Module Footprint: Standard rack-mount form factor measuring 33.02 cm high by 10.16 cm wide with a net weight of 1.20 kg (2.65 lbs).
