It provides thyristor firing control during normal and emergency generator shutdowns. The board contains two independent firing control circuits and supports synchronized firing of parallel SCRs. Furthermore, its capacitor storage circuit maintains sufficient DC voltage to trigger the SCR when external power is removed.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe DS200EXDEG1A serves as the main printed circuit board in the De-Excitation Module. This module removes stored energy from the generator field when the field breaker or contactors open during a normal or emergency shutdown.\u003c\/p\u003e\n\u003cp\u003eThe module also limits the voltage across the generator field and reduces the energy dissipated in the switching contactors. It works with a conduction sensor board, a steel flux-concentrating core, an SCR rated for either 53 mm or 77 mm configurations, and a sheet-metal mounting base.\u003c\/p\u003e\n\u003ch3\u003eThyristor Firing Control\u003c\/h3\u003e\n\u003cp\u003eThe DS200EXDEG1A contains thyristor and gate-control logic for triggering the SCR. The board can initiate firing through either of two control inputs or when the SCR anode-to-cathode voltage exceeds its breakover threshold.\u003c\/p\u003e\n\u003cp\u003eEach SCR requires an EXDE board for firing control. However, engineers can configure multiple boards to trigger parallel SCRs with synchronized firing pulses.\u003c\/p\u003e\n\u003ch3\u003eControl Circuits and Signal Connections\u003c\/h3\u003e\n\u003cp\u003eThe board provides two separate firing control circuits, designated Control Circuit 1 and Control Circuit 2. Each circuit has three associated terminal boards for control connections.\u003c\/p\u003e\n\u003cp\u003eThe firing pulse uses a 24 VDC signal applied across the designated terminal pairs:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eControl Circuit 1: Apply 24 VDC between 1TB-2 and 1TB-1.\u003c\/li\u003e\n\u003cli\u003eControl Circuit 2: Apply 24 VDC between 4TB-2 and 4TB-1.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA pulse transformer delivers the resulting firing signal to the SCR. Meanwhile, Berg jumpers isolate the pulse transformers of Control Circuits 1 and 2 from the SCR circuit, according to the board configuration.\u003c\/p\u003e\n\u003ch3\u003ePower Supply and Stored Energy\u003c\/h3\u003e\n\u003cp\u003eSeveral large capacitors on the DS200EXDEG1A maintain the DC voltage required by the firing circuits. Therefore, the board can generate an SCR firing pulse even after the external power supply has been removed. This stored-energy function supports the de-excitation sequence during power interruption.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDS200EXDEG1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eEX200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDe-Excitation Control Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExciter Connector Type\u003c\/td\u003e\n\u003ctd\u003e34\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Block\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e240 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 65 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.00 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e9.2 x 6.5 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManual\u003c\/td\u003e\n\u003ctd\u003eGEI-100195\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary function of the DS200EXDEG1A?\u003c\/p\u003e\n\u003cp\u003eA: The DS200EXDEG1A controls SCR firing in the generator de-excitation circuit.
